6 Functional Description
6.1 Operational Registers
6.1.1 R0, IAR (Indirect Addressing Register)
(Address: 00h)
R0 is not a physically implemented register. Its major function is to perform as an
indirect address pointer. Any instruction using R0 as a register, actually accesses the
data pointed by the RAM Select Register (R4).
6.1.2 R1, TCC (Timer Clock Counter)
(Address: 01h)
The Timer Clock Counter is incremented by an external signal edge applied to TCC, or
by the instruction cycle clock. It is written and read by the program as any other
register.
6.1.3 R2, PC (Program Counter)
(Address: 02h)
Figure 6-1 Program Counter Organization
The structure of R2 is depicted in Figure 6-1, Program Counter Organization.
The configuration structure generates 6K×13 bits on-chip ROM addresses to the
relative programming instruction codes.
12 •
The contents of R2 are all set to "0"s when a Reset condition occurs.
Product Specification (V1.0) 04.09.2015
(This specification is subject to change without prior notice)
EM78P516N
8-Bit Microcontroller
"JMP" instruction allows direct loading of the lower 10 program counter bits. Thus,
"JMP" allows the PC to jump to any location within a page.
"CALL" instruction loads the lower 10 bits of the PC, and PC+1 are pushed onto the
stack. Thus, the subroutine entry address can be located anywhere within a page.
"RET" ("RETL k", "RETI") instruction loads the program counter with the contents
at the top of the stack.
"ADD R2, A" allows a relative address to be added to the current PC, and the ninth
and above bits of the PC will increment progressively.
"MOV R2, A" allows loading of an address from the "A" register to the lower 8 bits of
the PC, and the ninth and tenth bits (A8 ~ A9) of the PC will remain unchanged.
The most significant bits (A10~A12) will be loaded with the content of PS0~PS1 in
the Status register (R3) upon execution of a "JMP" or "CALL" instruction.

PS0~PS2 are used to select a ROM page. User can use the PAGE instruction (e.g.
PAGE 1) or set PS2~PS0 bits to change the ROM page. When executing a "JMP",
"CALL", or other instructions which causes the program counter to be changed (e.g.
MOV R2, A), PS2~PS0 are loaded into the 11th and 12th bits of the program counter
where it selects one of the available program memory pages. Note that RET (RETL,
RETI) instruction does not change the PS2~PS0 bits. That is, the return will always be
to the page from where the subroutine was called, regardless of the current setting of
PS2~PS0 bits.
Bit 4 (T): Time-out bit. Set to “1” by the "SLEP" and "WDTC" commands or during

Note
(*) If the Watchdog function is enabled before going into Sleep mode, some circuits like
the Timer (its Clock Source is Fs) must stop counting.
If the Watchdog function is enabled before going into Sleep mode, some circuits like the
Timer (its Clock Source is the external pin) can still count and its interrupt flag can be active
at matching condition as corresponding interrupt is enabled. But the CPU cannot be
awakened by this event.
(**)
Switching Operation Mode at Sleep → Normal,
Green → Normal:
If the Timer Clock Source is Fm, the Timer/Counter must stop counting at Sleep or Green
mode. Then, the Timer can continue to count until the Clock Source is stable at Normal
mode. That the Clock Source is stable means the CPU starts to work at Normal mode.
Switching Operation Mode at Sleep → Green:
If the Timer Clock Source is Fs, the Timer must stop counting at Sleep mode. Then, the
Timer can continue to count until the Clock Source is stable at Green mode. That the Clock
Source is stable means the CPU starts to work at Green mode.
Switching Operation Mode at Sleep → Normal:
If the Timer Clock Source is Fs, the Timer must stop counting at Sleep mode. Then, the

Bit 7 (IRE): Infrared Remote Enable bit
IRE = "0": Disable the IR/PWM function. The state of P57/IROUT/AD2 pin is
determined by Bit 7 of IOC 50 if it is for IROUT.
IRE = "1": Enable IR or PWM function
Bit 6 (HF): High carry frequency
HF = "0": For PWM application, disable the H/W modulator function. The IROUT
waveform is generated according to high-pulse and low-pulse time as
determined by the respective high pulse and low pulse width timers.
Counter 2 is an independent auto reload timer.
HF = "1": For IR application mode, enable the H/W modulator function, the low
time sections of the generated pulse is modulated with the Fcarrier
frequency. The Fcarrier frequency is provided by Counter 2.
Bit 5 (LGP): IROUT for of low pulse width timer
LGP = "0": The high-pulse width timer register and low-pulse width timer is valid.
LGP = "1": The high-pulse width timer register is ignored. So the IROUT
waveform is dependent on the low-pulse width timer register only.
Bit 4: Not used
Bit 3 (IROUTE): Define the function of P57/IROUT/AD2 pin
IROUTE = "0": for bidirectional general I/O or AD2 pin
IROUTE = "1": for IR or PWM output pin, the control bit of P57 (Bit 7 of IOC50)
must be set to “0”

Bit 7 ~ Bit 0: These are high-pulse width timer buffers which user can read and write.
High-pulse width timer preset register is an eight-bit down-counter with 8-bit prescaler
used as IOCD0 to preset the counter and read the preset value. The prescaler is set by
the IOCA1 register. After an interrupt, it will reload the preset value.
For PWM or IR application, this control register is set as high pulse width.
If the high-pulse width timer clock source is FT ,
then

6.3 TCC and WDT Prescaler
Two 8-bit counters are available as prescalers for the TCC (Time Clock Counter) and
WDT (Watchdog Timer). The TCCP2~TCCP0 bits of the IOC71 register are used to
determine the ratio of the TCC prescaler. Likewise, the WDTP2~WDTP0 bits of the
IOC81 register are used to determine the WDT prescaler. The TCC prescaler
(TCCP2~TCCP0) is cleared by the instructions each time they are written into TCC,
while the WDT prescaler is cleared by the “WDTC” and “SLEP” instructions. Fig.7
depicts the circuit diagram of TCC and WDT.
R1 (TCC) is an 8-bit timer/counter. The clock source of TCC can be selected by
internal instruction clock or external signal input (edge selectable from the TCC control
register). If the TCC signal source is from the internal instruction clock, the TCC will be
incremented by 1 at every instruction cycle (without prescaler). If the TCC signal
source is from an external clock input, the TCC will be incremented by 1 at every falling
edge or rising edge of the TCC pin.
The Watchdog Timer is free running on sub-oscillator. The WDT will keep on running
even after the oscillator driver has been turned off. During Normal mode, Green mode,
or Idle mode operation, a WDT time-out (if enabled) will cause the device to reset. The
WDT can be enabled or disabled at any time during the Normal mode and Green mode
by software programming. Refer to WDTE bit of IOC81 register. The WDT time-out
period is equal to (prescaler × 256 / (Fs/2)).

6.4 I/O Ports
The I/O registers, (Port 5, Port 6, Port 7 and Port 8), are bi-directional tri-state I/O ports.
Port 6 and Port 8 are pulled-high internally by software; Port 6 is also pulled-low internally
by software. Furthermore, Port 6 has its open-drain output also through software. Port 6
and Port 8 features an input status changed interrupt (or wake-up) function and is
pulled-high by software. Each I/O pin can be defined as "input" or "output" pin by the I/O
control register (IOC50 ~ IOC80). The I/O registers and I/O control registers are both
readable and writable. The I/O interface circuits are shown in Figure 6-5.
Note: Open-drain, pull-high, and pull down are not shown in the figure.
Figure 6-5 Circuit of I/O Port and I/O Control Register for Port 5 ~ 8
6.5 Reset and Wake-up
A reset can be activated by
POR (Power-on Reset)
WDT timeout (if enabled)
/RESET pin goes to low
Note: The reset circuit is always enabled. It will reset the CPU at 1.7V.
Once a reset occurs, the following functions are performed
The oscillator is running, or will be started
The program counter (R2/PC) is set to all "0"
All I/O port pins are configured as input mode (high-impedance state)
The TCC/Watchdog timer and prescaler are cleared
When power is on, the Bits 5 and 6 of R3 and the upper two bits of R4 are
cleared.
Bits of the IOC71 register are set to all "1" except for Bit 6 (INT flag)
For other registers, see Table 2

6.6 Oscillator
6.6.1 Oscillator Modes
The EM78P516N can operate in three different oscillator modes:
a.) Main oscillator (R-OSCI, OSCO), such as RC oscillator with external resistor and
Internal capacitor mode (ERIC)
b.) Crystal oscillator mode
c.) PLL operation mode (R-OSCI connected to 0.01µF capacitor then connected to
Ground). User can select which mode by programming FMMD1 and FMMD0 in the
Code Options Register. The sub-oscillator can be operated in Crystal mode and
ERIC mode. Table 3 below shows how these three modes are defined.

6.6.3 Crystal Oscillator/Ceramic Resonators (Crystal)
This LSI can be driven by an external clock signal through the R-OSCI pin as shown in
Figure 6-7 below. In most applications, the R-OSCI pin and the OSCO pin can be
connected with a crystal or ceramic resonator to generate oscillation. Fig. 6-8 depicts
such circuit. Table 5 provides the recommended values of C1 and C2. Since each
resonator has its own attribute, user should refer to its specification for appropriate
values of C1 and C2. RS, a serial resistor, may be necessary for AT strip cut crystal or
low frequency mode.

6.6.4 RC Oscillator Mode with Internal Capacitor
If both precision and cost are taken into consideration, this LSI also offers a special
oscillation mode, which has an on-chip internal capacitor and an external resistor
connected to VDD. The internal capacitor functions as temperature compensator. In
order to obtain more accurate frequency, a precise resistor is recommended.

6.7 Power-on Considerations
Any microcontroller (as with this LSI) is not warranted to start operating properly before
the power supply stabilizes in a steady state. This LSI has an on-chip Power-on Reset
(POR) with detection level range as shown on the table below. The circuitry eliminates
the extra external reset circuit but will work well only if the VDD rises quickly enough
(50ms or less). However, under critical applications, extra devices are still required to
assist in solving power-on problems.

6.7.1 External Power-on Reset Circuit
This circuit implements an external RC to produce a reset pulse (see Figure 6-10). The
pulse width (time constant) should be kept long enough to allow VDD to reach minimum
operation voltage. This circuit is used when the power supply rise time is slow.
Because the current leakage from the /RESET pin is ± 5 µA, it is recommended that R
should not be greater than 40K. In this way, the voltage at Pin /RESET is held below
0.2V. The diode (D) acts as a short circuit at power-down. The capacitor, C, is
discharged rapidly and fully. Rin, the current-limited resistor, prevents high current
discharge or ESD (electrostatic discharge) from flowing into Pin /RESET.
Figure 6-10 External Power-on Reset Circuit
6.7.2 Residue-Voltage Protection
When battery is replaced, device power (VDD) is disconnected but residue-voltage
remains. The residue-voltage may trips below minimum VDD, but above zero. This
condition may cause poor power on reset. Figure 6-11 and Figure 6-12 show how to
build a residue-voltage protection circuit.

6.8 Interrupt
This LSI has eight interrupt sources as listed below:
TCC overflow interrupt
External interrupt P54/INT0 pin
External interrupt P55/INT1 pin
Counter 1 underflow interrupt
Counter 2 underflow interrupt
High-pulse width timer underflow interrupt
Low-pulse width timer underflow interrupt
Port 6, Port 8 input status change wake-up
Analog to Digital conversion completed
This IC has internal interrupts which are falling edge triggered or as follows:
TCC timer overflow interrupt
Four 8-bit down counter/timer underflow interrupt
If these interrupt sources change signal from high to low, the RF register will generate a
“1” flag to the corresponding register if the IOCF0 register is enabled.
RF is the interrupt status register. It records the interrupt request in flag bit. IOCF0 is
the interrupt mask register. Global interrupt is enabled by ENI instruction and disabled
by DISI instruction. When one of the interrupts (when enabled) is generated, it will
cause the next instruction to be fetch from Address 0003H~0018H according to
interrupt source.

EM78P516N
8-Bit Microcontroller
With this LSI, each individual interrupt source has its own interrupt vector as depicted in
Table 3. Before the interrupt subroutine is executed, the contents of the ACC and the
R3 register are initially saved by the hardware. After the interrupt service routine is
completed, the ACC and R3 are restored. The existing interrupt service routine does
not allow other interrupt service routine to be executed. Hence, if other interrupts occur
while an existing interrupt service routine is being executed, the hardware will save the
later interrupts. Only after the existing interrupt service routine is completed that the
next interrupt service routine is executed.

6.9 LCD Driver
This LSI can drive an LCD of up to 32 segments and 4 commons that can drive a total
of 4×32 dots. The LCD block is made up of an LCD driver, display RAM, segment
output pins, common output pins, and LCD operating power supply pins. This circuit
works on normal mode, green mode and idle mode. The LCD duty; bias; the number of
segment; the number of common and frame frequency are determined by the LCD
controller register.
The basic structure contains a timing control that uses a subsystem clock to generate
the proper timing for different duty and display accesses. The R9 register is a
command register for the LCD driver which includes LCD enable/disable, bias (1/2 and
1/3), duty (1/2, 1/3, 1/4), and LCD frame frequency control. The register RA is an LCD
contrast and LCD RAM address control register. The register RB is an LCD RAM data
buffer. LCD booster circuit can change the operation frequency to improve VLCD2 and
VLCD3 drive capability. The control register is described as follows.

6.10 Infrared Remote Control Application/PWM Waveform
Generation
This LSI can output infrared carrier in user-friendly or in PWM standard waveform. The IR
and PWM waveform generated functions include an 8-bit down count timer/counter,
high-pulse width timer, low-pulse width timer, and IR control register. The IR system block
diagram is shown in Fig. 6-20. The IROUT pin waveform is determined by IR control
register (RE), IOC90 (Counters 1 and 2 control register), IOCA0 (high-pulse width timer,
low-pulse width timer control register), IOCC0 (Counter 2 preset), IOCD0 (high-pulse width
timer preset register), and IOCE0 (low-pulse width timer preset register). Details on
Fcarrier, high-pulse time, and low pulse time are explained as follows:
If Counter 2 clock source is FT (this clock source can be set by IOC91), then
F carrier =
FT
2 × (1 + decimal of C ounter 2 preset value ( IOCC 0 )) × prescaler
If the high-pulse width timer clock source is FT (this clock source can be set by IOCA1), then
T high

The IROUT output waveform is further explained in the following figures:

when in low-pulse width time.
Figure 6-22
LGP=0, HF=0, the IROUT waveform cannot modulate Fcarrier
waveform when in low-pulse width time. So IROUT waveform is determined
by high-pulse time and low-pulse time. This mode can produce standard
PWM waveform.
Figure 6-23
LGP=0, HF=1, the IROUT waveform can modulate Fcarrier waveform
when in low-pulse width time. When IRE goes from high to low, the output
waveform of IROUT will keep on transmitting until high-pulse width timer
interrupt occurs.
Figure 6-24
LGP=0, HF=0, the IROUT waveform can not modulate Fcarrier
waveform when in low-pulse width time. So IROUT waveform is determined
by high-pulse time and low-pulse time. This mode can produce standard
PWM waveform. When IRE goes from high to low, the output waveform of
IROUT will keep on transmitting till high-pulse width timer interrupt occurs.

ignored. So IROUT waveform output from low-pulse width timer is
established.

Analog-to-Digital Converter (ADC)
The analog-to-digital circuitry consists of an 16-bit analog multiplexer; two control registers
(ADCR1/BANK1 RA and ADISR/BANK1 RB), two data registers (ADDH/BANK1 RD and
ADDL/BANK1 RC) and an ADC with 12-bit resolution as shown in the functional block diagram
below. The analog reference voltage (Vref) and the analog ground are connected via separate
input pins.
The ADC module utilizes successive approximation to convert the unknown analog signal into a
digital value. The result is fed to the ADDH and ADDL. Input channels are selected by the
analog input multiplexer via the ADISR register bits. Connecting to the external VREF is more
accurate than connecting to the internal VDD.

6.11.2 ADC Sampling Time
The accuracy, linearity, and speed of the successive approximation of the AD converter
are dependent on the properties of the ADC and the comparator. The source impedance
and the internal sampling impedance directly affect the time required to charge the
sample holding capacitor. The application program controls the length of the sample
time to meet the specified accuracy. Generally speaking, the program should wait for 2 µs
for each KΩ of the analog source impedance and at least 2 µs for the low-impedance
source. The maximum recommended impedance for analog source is 10KΩ at Vdd=5V.
After the analog input channel is selected, this acquisition time must be done before the
conversion is started.
6.11.3 AD Conversion Time
CKR1 and CKR0 select the conversion time (Tct), in terms of instruction cycles. This
allows the MCU to run at the maximum frequency without sacrificing the AD conversion
accuracy. For the EM78P516N, the conversion time per bit is about 1µs. The table
below shows the relationship between Tct and the maximum operating frequencies.

NOTE
■ Pin not used as an analog input pin can be used as regular input or output pin.
■ During conversion, do not perform output instruction to maintain precision for all of the
pins.
6.11.4 ADC Operation during Sleep Mode
In order to obtain a more accurate ADC value and reduce power consumption, the AD
conversion remains operational during sleep mode. As the SLEP instruction is
executed, all the MCU operations will stop except for the Oscillator, TCC, Timer 1,
Timer 2, Timer 3, and AD conversion.
AD Conversion is considered completed as determined by:
1. The ADRUN bit of BANK1 RA register is cleared to “0”.
2. Waking up from AD conversion (where it remains in operation during sleep mode).
The results are fed into the ADDH and ADDL registers when conversion is completed.
If the ADIE is enabled, the device will wake up. Otherwise, the AD conversion will be
shut off, no matter what the status of the ADPD bit is.

6.11.5 Programming Process/Considerations
6.11.5.1 Programming Process
Follow these steps to obtain data from the ADC:
1. Write to the eight bits (ADE14: ADE0) on the BANK1 R8 & R9 (ADSR1&ADSR2)
register to define the characteristics of R5,R6 and R8 (digital I/O, analog channels,
or voltage reference pin)
2. Write to the Bank1 RA/ADCR1 register to configure the AD module:
a) Select ADC input channel (ADIS3:ADIS0)
b) Define AD conversion clock rate (CKR1:CKR0)
c) Select the VREFS input source of the ADC
d) Set the ADPD bit to 1 to begin sampling
3. Set the ADIE bit, if the wake-up function is employed
4. Write “ENI” instruction, if the interrupt function is employed
5. Set the ADRUN bit to 1
6. Write “SLEP+NOP” instruction
8. Wait for wake-up or for the ADRUN bit to be cleared to “0”.
9. Read the ADDH and ADDL conversion data registers. If the ADC input channel
changes at this time, the ADDH and ADDL values can be cleared to ‘0’.
10. Clear the interrupt flag bit (ADIF).
11. For next conversion, go to Step 1 or Step 2 as required. At least two Tct is required
before the next acquisition starts.
NOTE
In order to obtain accurate values, it is necessary to avoid any data transition on the I/O pins
during AD conversion.

6.13 Instruction Set
Each instruction in the instruction set is a 13-bit word divided into an OP code and one
or more operands. Normally, all instructions are executed within one single instruction
cycle (one instruction consists of 2 oscillator periods), unless the program counter is
changed by instruction "MOV R2,A", "ADD R2,A", or by instructions of arithmetic or
logic operation on R2 (e.g. "SUB R2,A", "BS(C) R2,6", "CLR R2", ⋅⋅⋅⋅). In this case, the
execution takes two instruction cycles.
If for some reasons, the specification of the instruction cycle is not suitable for certain
applications, try modifying the instruction as follows:
Execute within two instruction cycles the "JMP", "CALL", "RET", "RETL", and "RETI"
instructions, or the conditional skip instructions ("JBS", "JBC", "JZ", "JZA", "DJZ",
"DJZA") which were tested to be true. Also execute within two instruction cycles the
instructions that are written to the program counter.
Additionally, the instruction set offers the following features:
(1) Every bit of any register can be set, cleared, or tested directly.
(2) The I/O register can be regarded as general register. That is, the same instruction
can operate on I/O register.

E.1 Address Trap Detect
An address trap detect is one of the MCU embedded fail-safe functions that detects
MCU malfunction caused by noise or the like. Whenever the MCU attempts to fetch an
instruction from a certain section of ROM, an internal recovery circuit is auto started. If
a noise-caused address error is detected, the MCU will repeat execution of the
program until the noise is eliminated. The MCU will then continue to execute the next
program.
