PCE84C882
The duty cycle of each PWM output is dependent upon the
programmable contents of its associated data latch
(Registers 10 to 17 respectively, Register 15 is not used
as there is no PWM5 output). As the clock frequency of
each PWM circuit is 1⁄3 × fxtal, the pulse width of the pulse
generated can be calculated as shown below.
ANALOG (DC) CONTROL
The PCE84C882 has eight Pulse Width Modulated (PWM)
outputs for analog control purposes e.g. brightness,
contrast, H-shift, V-shift, H-width, V-size, E-W, R (or G or
B) gain control etc. Each PWM output generates a pulse
pattern with a programmable duty cycle.
3 × ( PWMn )
Pulse width = ---------------------------------f xtal
The eight PWM outputs are specified below:
• 3 PWM outputs with 6-bit resolution (PWM4, 6 and 7)
• 4 PWM outputs with 7-bit resolution (PWM0 to PWM3)
Where (PWMn) is the decimal value held in the data latch.
• 1 PWM output with 14-bit resolution (PWM8).
The maximum repetition frequency (fPWM) of the 6 and
7-bit PWM outputs is shown below.
The 6 and 7-bit PWM outputs are described in Section 7.1;
the 14-bit PWM output is described in Section 7.2 and a
typical PWM output application is described in Section 7.3.
7.1

For the 6-bit PWM outputs: f PWM = --------192
6 and 7-bit PWM outputs

For the 7-bit PWM outputs: f PWM = --------384
PWM outputs PWM0 to PWM4, PWM6 and PWM7, share
the same pins as Derivative Port lines DP00 to DP04,
DP06 and DP07, respectively. Selection of the pin function
as either a PWM output or a Derivative Port line is
achieved using the appropriate PWMnE bit in Register 21
(see Table 38).
The block diagram for the 6 and 7-bit PWM outputs is
shown in Fig.5.
The polarity of the PWM outputs is programmable and is
selected by the P7LVL or the P6LVL bit in Register 23
(see Section 12.2). The state of the P7LVL bit determines
the polarity of the 7-bit PWMs; the state of the P6LVL bit
determines the polarity of the 6-bit PWMs.

14-bit PWM output

PWM8 shares the same pin as Derivative Port line DP13.
Selection of the pin function as either a PWM output or as
a Derivative Port line is achieved using the PWM8E bit in
Register 22 (see Section 12.1).
COARSE ADJUSTMENT
An active HIGH pulse is generated in every subperiod; the
pulse width being determined by the contents of PWM8H.
The coarse output (OUT1) is LOW at the start of each
subperiod and will remain LOW until the time
[ 3 ⁄ f xtal × ( PWM8H + 1 ) ] has elapsed. The output will
The block diagram for the 14-bit PWM output is shown in
Fig.7 and comprises:

subperiod. The coarse pulse width may be calculated as
shown below.

(Register 19)
• 14-bit data latch (PWMREG)
• 14-bit counter
• Coarse pulse controller
7.2.2
• Fine pulse controller
Fine adjustment is achieved by generating an additional
pulse in specific subperiods. The pulse is added at the
start of the selected subperiod and has a pulse width of
3/fxtal. The contents of PWM8L determine in which
subperiods a fine pulse will be added. It is the logic 0 state
of the value held in PWM8L that actually selects the
subperiods. When more than one bit is a logic 0 then the
subperiods selected will be a combination of those
subperiods specified in Table 3. For example, if
PWM8L = 111 1010 then this is a combination of:
• Mixer.
Data is loaded into the 14-bit data latch (PWMREG) from
the two 7-bit data latches (PWM8H and PWM8L) when
either of these data latches is written to. The upper seven
bits of PWMREG are used by the coarse pulse controller
and determine the coarse pulse width; the lower seven bits
are used by the fine pulse controller and determine in
which subperiods fine pulses will be added. The outputs
OUT1 and OUT2 of the coarse and fine pulse controllers
are ‘ORED’ in the mixer to give the PWM8 output. The
polarity of the PWM8 output is programmable and is
selected by the P8LVL bit in Register 23, this is described
in Section 12.2.
FINE ADJUSTMENT
• PWM8L = 111 1110: subperiod 64 and
• PWM8L = 111 1011: subperiods 16, 48, 80 and 112.
Pulses will be added in subperiods 16, 48, 64, 80 and 112.
This example is illustrated in Fig.10.
As the 14-bit counter is clocked by 1⁄3 × fxtal, the repetition
times of the coarse and fine pulse controllers may be
calculated as shown below.
When PWM8L holds 111 1111 fine adjustment is inhibited
and the PWM8 output is determined only by the contents
of PWM8H.

A typical PWM output application
A typical PWM application is shown in Fig.11. The buffer is
used to reduce jitter on the OSD. R1 and C1 form the
integration network the time constant of which should be at
least 5 times greater than the repetition period of the PWM
output pattern. In order to smooth a changing PWM output
a high value of C1 should be chosen. The value of C1 will
normally be in the range 1 to 10 µF. The potential divider
chain formed by R2 and R3 is used only when the output
voltage is to be offset. The output voltages for this
application are calculated using Equations (1) and (2).

The loop from the PWM pin through R1 and C1 to VSS will
radiate high frequency energy pulses. In order to limit the
effect of this unwanted radiation source, the loop should
be kept short and a high value of R1 selected. The value
of R1 will normally be in the range 3.3 to 100 kΩ. It is good
practice to avoid sharing VSS (pin 30) with the return leads
of other sensitive signals.

8.1
ANALOG-TO-DIGITAL CONVERTER (ADC)
Conversion algorithm
The single channel ADC comprises a 4-bit
Digital-to-Analog Converter (DAC); a comparator; an
analog channel selector and control circuitry. As the digital
input to the 4-bit DAC is loaded by software (a subroutine
in the program), it is known as a software ADC. The block
diagram is shown in Fig.12.
There are many algorithms available to achieve the ADC
conversion. The algorithm described below and shown in
Fig.13 uses an iteration process.
The ADC input ADC2, shares the same pin as Derivative
Port line DP12. Selection of the pin function as either an
ADC input or as a Derivative Port line is achieved using bit
ADCE2 in Register 22. When ADCE2 = 1, the ADC
function is enabled (see Section 12.1).
2. Set the digital input to the DAC to 1000. The digital
input to the DAC is selected using bits DAC3 to DAC0
in Register 20.
1. Enable and then select the ADC2 channel for
conversion. Channel selection is achieved using bits
ADCS1 and ADCS0 in Register 20.
3. Determine the result of the compare operation. This is
achieved by reading the COMP bit in Register 20
using the instruction MOV A, D20. If COMP = 1; the
analog input voltage is higher than the reference
voltage (Vref). If COMP = 0; the analog input voltage is
lower than the reference voltage (Vref).
The ADC channel selector is controlled by the ADCS1 and
ADCS0 bits in Register 20. As the PCE84C882 provides
only one ADC channel, ADCS1 bit must be set to a logic 1
and ADCS0 bit must be set to a logic 0. All other settings
are invalid.
4. If COMP = 1; then the analog input voltage is higher
than the reference voltage (Vref) and therefore the
digital input to the DAC needs to be increased. Set the
input to the DAC to 1100.
The 4-bit DAC analog output voltage (Vref) is determined
by the decimal value of the data held in bits DAC0 to DAC3
of Register 20. Vref is calculated as shown in Equation (3)
and Table 4 lists the Vref values assuming VDD = 5 V.
V DD
V ref = ---------- × ( DAC value + 1 )
(3)
16
5. If COMP = 0; then the analog input voltage is lower
than the reference voltage (Vref) and therefore the
digital input to the DAC needs to be decreased. Set the
input to the DAC to 0100.
When the analog input voltage is higher than Vref, the
COMP bit in Register 20 will be HIGH.

6. Determine the result of the compare operation by
reading the COMP bit in Register 20.

If COMP = 1; then the analog input voltage is still
greater than Vref and therefore the digital input to the
DAC needs to be increased again. Set the input to the
DAC to 1110.
If COMP = 0; then the analog input voltage is now less
than Vref and therefore the digital input to the DAC
needs to be decreased. Set the input to the DAC to
1010
8. For the DAC = 0100 case
If COMP = 1; then the analog input voltage is now

DAC needs to be increased. Set the input to the DAC
to 0110.
If COMP = 0; then the analog input voltage is still lower
than Vref and therefore the digital input to the DAC
needs to be decreased again. Set the input to the DAC
to 0010.

9. The operations detailed in 6, 7 and 8 above are
repeated and each time the digital input to the DAC is
changed accordingly; as dictated by the state of the
COMP bit. The complete process is shown in Fig.13.
Each time the DAC input is changed the number of
values which the analog input can take is reduced by
half. In this manner the actual analog value is honed
into. The value of the analog input (VA) is determined
using Equation (4):
V DD
V A = ---------- × ( DAC value + 1 )
16

As the conversion time of each compare operation is
greater than 6 µs but less than 9 µs; a NOP instruction is
recommended to be used in between the instructions that
change the value of Vref; select the ADC channel and read
the COMP bit.

PCE84C882
The input voltage generated by the operation of any key
(ignoring the effect of the 100 kΩ resistor) can be
calculated as follows:
Typical ADC application
The ADC2 channel of the PCE84C882 can be used in
keypad applications to detect and identify the operation of
individual keys. The circuit for a 14-key application is
shown in Fig.14.
V ADCn =
When no key is depressed the input voltage at the
DP12/ADC2 pin will be greater than 15⁄16 × VDD and if the
DAC value selected is 1110 then the COMP bit will be
HIGH. When any key is depressed the input voltage at the
DP12/ADC2 pin will change, and as each key will generate
its own unique input voltage, this can be measured by the
ADC2 channel and the actual key depressed can then be
identified.
( n – 0.5 )
------------------------ × V DD
16
Where n is the key number and can take any integer value
in the range 1 to 14.
The input voltage at the ADC input will be influenced by the
tolerance of the resistors and the length of the cable
connecting the keypad to the monitor. In the worse case
situation this may reduce the number of keys that can be
uniquely detected and identified.

PCE84C882
ON SCREEN DISPLAY (OSD)
9.4
The OSD feature of the PCE84C882 enables the user to
display information on the monitor screen. Display
information can be created using 62 customer designed
characters, a space character and a carriage return code.
The OSD block diagram is shown in Fig.15.
9.1
The on-chip oscillator generates an OSD clock that is
auto-sync with Hsync. The frequency of the OSD clock is
programmable and is determined by the contents of the
7-bit counter (Register 25) and also the prescaler value
selected by mask option (a prescaler value of 2 or 4 can be
selected). For 31 to 64 kHz auto-sync monitors, a
prescaler value of 4 is selected; for 31 to 90 kHz auto-sync
monitors a prescaler value of 2 or 4 can be selected.
Horizontal starting position control
The horizontal starting position counter is incremented
every OSD clock after Hsync becomes inactive and is
reset when Hsync becomes active. The horizontal starting
position of the display row is determined by the contents of
Register 36; 1 of 64 positions may be selected as
explained in Section 12.6.
The OSD clock frequency is calculated as follows:
f OSD = f Hsync × ( 2 or 4 ) × ( Register 25 )
Where (Register 25) denotes the decimal value held in
Register 25.
The block diagram of the OSD clock is shown in Fig.17.
The internal reference frequency is connected to Hsync,
and if the frequency of Hsync changes the output
frequency (fOSD) will be changed linearly. The internal
Hsync signal is designed active HIGH, consequently fPLL is
synchronized with the falling edge of this signal (end of
back-tracing period).
The polarity of the active state of the HSYNCN input is
programmable and is determined by the Hp bit in
Register 34; see Section 12.4. The active HIGH and active
LOW states as selected by the Hp bit are shown in Fig.16.
9.2
Vertical starting position control
The vertical starting position counter is incremented every
Hsync cycle and is reset when Vsync becomes active. The
vertical starting position of the display row is determined by
the contents of Register 35; 1 of 64 positions may be
selected as explained in Section 12.5.
The OSD clock is enabled/disabled by the state of the EN
bit in Register 34; see Section 12.4. When the OSD clock
is disabled the oscillator remains active, therefore the
transient time from the OSD clock start-up to locking into
the external Hsync signal is reduced. To ensure that the
OSD clock is stable and in-phase with Hsync before the
display is enabled, the End bit of the Space Code can be
used to enable the OSD feature; the procedure is as
follows.
To achieve the same starting position with different display
resolutions, only the contents of Register 35 need to be
changed, the contents of Register 36 remain the same.
The lowest vertical starting position that can be selected,
is located on the 256th scan-line. However, lower positions
may be achieved using the Carriage Return Code.
1. Write a Space Code to address 00H of display RAM,
the End bit value is logic 1.
When the selected horizontal and vertical starting
positions are reached on screen; the OSD is enabled. The
character selected in display RAM is then displayed.
2. Set the EN bit in Register 34 to logic 0.
3. Write a Space Code to address 00H of display RAM,
the End bit value is logic 0.
The polarity of the active state of the VSYNCN input is
programmable and is determined by the Vp bit in Register
34; see Section 12.4. The active HIGH and active LOW
states as selected by the Vp bit are shown in Fig.16.
9.3
Two dedicated power pins: VDDP and VSSP, isolate the
oscillator supplies from other circuits thus reducing any
radiated noise that might effect the Voltage Controlled
Oscillator. Radiated noise is further reduced because as
the oscillator is always active after power-on when the
OSD clock is enabled no large currents will flow (as in the
case of RC or LC oscillators).
Vertical jumping cancelling
If the H-shift of the monitor is altered then vertical jumping
of the OSD may occur if the rising or falling edges of the
Hsync and Vsync signals are too close. The PCE84C882
has on-chip vertical cancelling circuitry that prevents this
from happening.

10 DISPLAY RAM ORGANIZATION
10.1
Description of display RAM codes
The display RAM is organized as 64 × 10 bits. The general
format of each RAM location is as follows. Bits <9-4> hold
character data (62 customer designed character fonts plus
two reserved codes). Bits <3-0> contain the attributes of
the character font, for example colour, character size,
blinking etc.
There are three data formats for display RAM code:
1. Character Font Code
2. Carriage Return Code
3. Space Code.
The three data formats are shown in Tables 5, 6 and 7.
Display RAM is updated during the vertical back-tracing
period (Vsync will generate an interrupt when it becomes
active).

If bits <9-4> hold 3FH, then this is the Space Code. A
transparent pattern, equal to one character width, will be
displayed on the screen. Bits <3-1> determine the
background colour of the characters including the Space
Code in Box shadowing mode, but following the Space
Code in North shadowing mode. See Sections 12.4 and
12.3.1 for more details. Background colour selection is the
same as foreground colour selection. Bit <0> is the
End-of-Display bit and indicates the end of display of the
current screen before exhaustion of display RAM (i.e.
before the 64th RAM location). The format of the Space
Code is shown in Table 7.
Selection of Blinking function
CARRIAGE RETURN CODE
If bits <9-4> hold 3EH, then this is the Carriage Return
Code. The current display line is terminated (a transparent
pattern appears on the screen) and the next character will
be displayed at the beginning of the next line. Bits <3-2>
select the size of the of the character to be displayed on
the next line. Bits <1-0> determine the spacing between
lines of displayed characters. Spacing is a multiple of the
number of horizontal scan lines. The format of the Carriage
Return Code is shown in Table 6.

Writing character data into display RAM
The procedure for writing character data into the display
RAM is as follows:
Loading character data into display RAM
1. Select the start address in display RAM. The start
address is stored in DCRAR and can take any value
between 0 and 63.
Three Derivative Registers are used to address and load
data into the display RAM. These registers are described
below.
2. Load the character attributes into DCRTR. If the
attributes of a series of displayed characters are the
same, only DCRCR needs to be updated.
10.3
10.3.1
3. Load the character data into DCRCR. The character
data will specify either a Character Font Code, the
Carriage Return Code or the Space Code. This
operation loads the selected RAM location with the
data held in registers DCRTR and DCRCR. The
address held in DCRAR is then incremented by ‘1’
pointing to the next RAM location in anticipation of the
next operation.
DCR ADDRESS REGISTER (DCRAR)
This is Derivative Register 30 and holds the address of the
location in display RAM to which the data held in registers
DCRTR and DCRCR will be written to. 1 of 64 locations
can be addressed. Bits 7 and 6 are reserved. The contents
of this register are automatically incremented after each
write operation to a RAM address, and become zero on
overflow.
After a master reset the contents of DCRAR, DCRTR and
DCRCR are zero.

The combination of two cells in a horizontal direction is
straight forward and requires no special precautions to be
taken. When combining character cells in this manner all 4
Background/Shadowing modes are available. An example
of combining two character font cells in a horizontal
direction is shown in Fig.20.
11 CHARACTER ROM
64 character fonts may be held in ROM; 62 customer
selected character fonts plus the Carriage Return Code
and the Space Code. Customer selected fonts are mask
programmable. Each character font is stored in a 12 × 19
dot matrix. However, only elements in Rows 1 to 18 can be
selected as visible dots on the screen. Row 0 is only used
for the combination of two characters in a vertical direction
when North shadowing mode is selected.
11.1
However, the combination of two character font cells in a
vertical direction is more difficult and care must be taken;
otherwise, the new pattern may be created with gaps in its
shadowing. An example of a character pattern with gaps is
shown in Fig.21. Providing the steps listed below are
followed no problems with shadowing will occur.
Character ROM address map
Figure 18 shows the ROM address map. Addresses 3EH
and 3FH hold the reserved codes for carriage return and
space functions, respectively. Addresses (00H to 3DH)
hold the customer selected character font codes.
11.2
• The line spacing between two rows of characters must
be programmed to 0H. This procedure is explained in
Section 10.1.2.
• If the North shadowing mode is selected then when
combining two character cells in a vertical direction
Row 0 must contain the same bit pattern as held in
Row 18 of the character directly above it. This is shown
in Fig.22.
Character ROM organization
ROM is divided into two parts: ROM1 and ROM2. The
organization of the bit patterns stored in ROM 1 and
ROM 2 and also the file format to submit to Philips for
customized character sets is shown in Fig.19. Regarding
Fig.19 the following points should be noted.
• If North shadowing is not required then Row 0 should
contain all zeros.
1. Row 0 of each font is reserved for vertical combination
of two fonts.
0
2. Binary 1 denotes visual dots.
3. ROM1 and ROM2 data files are in INTEL hex format
on a byte basis. Each byte is structured high nibble
followed by low nibble.
4. The unused last byte of each font in ROM1 must be
filled with FFH.
5. The unused last 21⁄2 bytes in ROM2 must be filled with
the same data as held in the corresponding address in
ROM1.
6. The data bytes of the last 2 reserved fonts (Carriage
Return and Space Codes) should be filled with 00H.
Mask Programmable Font
7. CS denotes Checksum.
reserved code
A software package (OSDGEM) that assists in the design
of character fonts on-screen and that also automatically
generates the bit pattern HEX files is available on request.

VINT
VSYNCN/SIO interrupt indication bit. This bit indicates which of the two possible
interrupt sources, the Vsync signal (at the VSYNCN pin) or the SIO, generated the
interrupt. The interrupt causes the program to jump to the I2C interrupt subroutine at
address 05H. If VINT = 1; then the interrupt was generated by Vsync. If VINT = 0; then
the I2C-bus generated the interrupt. This bit must be reset after the interrupt has been
serviced, otherwise additional unwanted interrupts will be generated.
6
VIEN
VSYNCN interrupt enable bit. When the SIO interrupt is enabled and VIEN = 1; the
Vsync signal (at the VSYNCN pin) will generate an interrupt to the CPU. The VSYNCN
interrupt is edge-triggered and can be selected to become active, using the Vp bit in
Register 34, on the rising or falling edge of the Vsync signal. In order to generate a
VSYNCN interrupt at the start of the vertical back tracing period, the Vp bit must be set
correctly; see Section 12.4. The VSYNCN interrupt and the I2C-bus interrupt share the
same interrupt vector.

• In Mode 2: Box shadowing mode. The Space Code is
displayed as a transparent pattern with selected
background colour. This will also be the background
colour of the character following the Space Code.
However, when the Space Code is used as an end bit, it
will be displayed as a transparent pattern superimposed
on the video (see Fig.30). The Carriage Return Code in
Mode 2 is also displayed as a transparent pattern
superimposed on the video signal.
THE DISPLAY OF SPACE AND CARRIAGE RETURN
CHARACTERS IN THE 4 DISPLAY MODES
Figures 23 to 26 show the display of Space and Carriage
Return Characters in the 4 display modes, with the
Blinking function ON and OFF.
• Mode 0: No background mode. Both the Space Code
and the Carriage Return Code are displayed as
transparent (no bit) patterns, with the video signal as the
background. This is shown in Fig.23.
• Mode 3: Frame shadowing mode. The Space Code and
the Carriage Return Code are both displayed as
transparent patterns with background colour (see
Fig.26).
• Mode 1: North shadowing mode. Both codes are
displayed in the same manner as for Mode 0. This is
shown in Fig.24.

Mode 1: North shadowing mode. The characters’ shadows are generated as if a light
source was placed North of the character (see Fig.28). Character shadowing only
appears within the cell boundary. Consequently, if Row 18 contains a bit pattern then
North shadowing will not be shown on the screen (see Fig.20). The depth of shadow
displayed is dependent upon the character size; characters with sizes of 1H/1V; 1H/2V
and 1H/3V have a depth of shadow equivalent to 1 scan line whereas a character of
size 1H/4V has a depth of shadow equivalent to 2 scan lines. Examples of characters
with North shadowing, for the 4 character sizes, are shown in Fig.29.

Mode 2: Box shadowing mode. A background dot matrix of 12 × 18 bits surrounds the
character font; where there is no foreground dot a background dot is displayed (see
Fig.30).

Mode 3: Frame shadowing mode. A background colour fills the whole screen when no
bit patterns are being displayed (see Fig.31). 1 of 8 background colours can be selected
using Derivative Register 37; the default background colour is blue.

Number of characters per row
To cater for the variable display resolutions (i.e. 640 x 400,
640 × 480, 800 × 600, 1024 × 768 and 1 280 × 1 024) of
auto-sync monitors, the PCE84C882 offers a choice of 4
different character sizes: 1H/1V, 1H/2V, 1H/3V and 1H/4V.
This allows the height of displayed characters to be of
similar size even when the monitors resolution is changed
(see Table 35).
The number of characters per row is a function of
character width. The width of the character displayed is
only dependent upon the value held in the 7-bit
programmable counter (PLLCN) and is not affected by a
change in horizontal resolution (any change in fHsync will be
reflected by a linear change in the frequency of the OSD
clock).
Table 35 Recommended character size selection for
different display resolutions
The maximum number of characters per row can be
determined by calculating the number of OSD clock pulses
that occur during the Hsync active period and dividing the
result by the number of horizontal dots in the character
matrix (which is 12). If Hsync is assumed to be active for
85% of its cycle period then the maximum number of
characters per row (N) can be calculated as follows:
RESOLUTION
0.85 × f OSD
N = ---------------------------12 × f Hsync

Number of rows per frame
14 I2C-BUS INTERFACE
The number of rows per frame is a function of character
height and the spacing between the rows of characters.
The PCE84C882 has an on-chip I2C-bus interface that can
be used in master or slave mode. Full details of the I2C-bus
are given in the document “The I2C-bus and how to use it”.
This document may be ordered using the code
9398 393 40011.
The height of a character displayed on the screen is
determined by the number of visible scan lines per frame
and the character size. The number of scan lines is
dependent upon the resolution of the monitor; character
size is selected by the user (see Section 10.1.2). The
PCE84C882 also provides a choice of four inter-line
spaces: 0H, 4H, 8H and 12H (see Section 10.1.2).
The I2C-bus interface lines SDA and SCL share the same
pins as Derivative Port lines DP20 and DP21 respectively.
Selection of the pin function as either an I2C-bus line or a
Derivative Port line is achieved using the SDAE and SCLE
bits in Derivative Register 22 (see Section 12.1). Only port
Option 2 is available for both of these pins.
If the inter-line spacing is assumed to be zero then the
number of rows per frame (R) can be calculated by dividing
the number of visible scan lines (SL) by the character size
(CS) and dividing the result by the number of vertical dots
in the character matrix (which is 18). This can be
expressed mathematically as follows:
SL
R = --------------------18 × CS
Table 35 shows the number of rows per frame for different
horizontal resolutions.

15 8-BIT COUNTER (T3)
One application for this counter is in the frequency
measurement of the Hsync signal.
The block diagram of the 8-bit counter is shown in Fig.33.
A Schmitt trigger is used at the input for noise rejection and
also to shape the input signal into a square wave. The T3
input is sampled at a frequency of 1⁄3 × fosc by the sample
clock which synchronizes the internal T3 clock and the
read operation of Derivative Register 24. The rising edge
of the input increments the ripple counter by 1.
handbook, halfpage
tH
0.9 VDD
0.1 VDD
The contents of T3 may be read using the instruction
MOV A, D24 (where D24 is Derivative Register 24). As
soon as the data is read, the counter is reset to zero. A
counter overflow or Power-on-reset also resets the
counter contents to zero.
tr
tf

tL
If the rising and falling edges of the input pulse are less
than 30 ns then the minimum pulse width that the T3 input
will recognise is 3/fosc + 100 ns. If the system clock is
10 MHz then the minimum pulse width is 400 ns. In some
display modes, the active pulse width of the Hsync signal
can be less than 400 ns. In this situation, extra hardware
circuitry may be necessary.

PCE84C882
17 DERIVATIVE REGISTERS
The PCE84C882 has 29 Derivative Registers. The Derivative Port I/O registers are located at addresses 00 to 05H.
When DP0TR, DP1TR and DP2TR are read the data is read directly from the pin. However, when DP0R, DP1R and
DP2R are read the data is read from the port latch (see Figs 34 to 36 for the port configuration).
As the PCE84C882 has no PWM5 output the corresponding enable bit (PWM5E) in the PWME Register (address 21H)
must be set to a logic 0.
As the PCE84C882 has only one ADC channel the channel select bits (ADCS1 and ADCS0) in the ADCCN Register
(address 20H) and the pin function enable bits (ADCE1 and ADCE0) in the CON1 Register (address 22H) must be set
to the values specified in Chapter 8.

23 SOLDERING
23.1
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
23.2
Soldering by dipping or by wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
23.3
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
