GENERAL DESCRIPTION
The Z02205 V.22bis Modem Controller serves as the modem controller in embedded V.22bis modem applications.
A complete modem can be made by adding ZiLOG data
pump (Z02201), phone line interface, and the required DTE
interface. The Z02205 has been designed for low-cost use
and includes a glueless interface to the ZiLOG data pumps.
The Z02205 is ideal for applications where small size and
low power consumption are requirements.
The Z02205 operates over dial-up telephone connections,
provides auto-dial and ring detect, and operates in either
SYNC or ASYNC modes.
The Z02205 includes AT command and modem control
firmware in on-chip ROM. It also includes enhanced wakeup circuitry, programmable Watch-Dog Timers (WDT), and
low-noise/EMI options.
AT commands stored on-chip in ROM provide control over
the following modem controller functions:

Standard Z02205 sample devices and demonstration boards
contain controller code tailored for operation on the North
American phone network. For production usage, customers
must modify the controller code to meet the requirements
of their particular country and application.

AT COMMAND SET
Command lines are typed to the modem from the terminal
when the modem is in the Idle or Command state. The modem does not execute any commands from a command line
until the command line is ended by the end of line character
<CR>. A command line is a string of characters starting with
A and T characters and ending with a special end-of-line
character, <CR>. Characters typed before the AT are ignored. Command lines contain no more than 40 characters
after the AT (not counting spaces). The modem does not execute any commands in a command line that is too long.
To Echo command line characters, use the E1 command.
Typing mistakes can be aborted by using a special BackSpace character, <BS>, after the initial A and T characters
are entered.
A partial command line can be aborted by typing a Ctrl-X
character. The modem returns an OK result code and ignores the partial AT command line.
Command lines may contain several commands one after
another. The ANSWER (A), DIAL (D), and GO ON-LINE (O)
commands cause any subsequent commands in the command line to be ignored.
Command Line Execution
The characters in a command line execute one at a time. Any
unexpected characters, except control characters, stop command line execution and return an ERROR result code. Unexpected characters include numbers outside the range of
values accepted by the command. All control characters in
a command line except Ctrl-X and the special characters
such as <CR> and <BS> are ignored.
The numerical argument of a command is assumed to be 0
if not provided. For example, the commands ATH<CR> and
ATH0<CR> both hang up the telephone line.
When the modem has executed a command line, the result
code of the last command executed is returned to the terminal.
If the value to be written to a modem S-register is outside
the range of values accepted by the S-register, then its value
is set to the nearest allowed value.
Leading zeros in numeric arguments, including S-register
numbers, are ignored. For example, ATS1 is 2 and ATS01
is 2 both set S-register S1 to 2.
All numeric arguments, including S-register numbers, are
decimal.
AT Command Prefix
Each modem command line begins with the letters A and
T. The modem uses these characters to determine the data
rate and parity of data from the terminal.
A/ Repeat Last Command
To repeat the commands in the last command line, type the
letters A and / instead of A and T.
<CR>End Of Line Character
This character is typed to end a command line. The value
of the <CR> character is stored in S-register S3. The default
is 13, the ASCII carriage return character.
When the <CR> character is entered, the modem executes
the commands in the command line.
Note: Default values in Table 2 are denoted by bold.

Table 2. AT Command Set
Command
A

&C
Function and Description
Answer
The A command causes the modem go off-hook and respond to an incoming call. Uses
this command after the modem has returned the RING result code.
When modems successfully complete the answering process, they each return a
CONNECT result code and enter the On-Line state.
If no transmit carrier signal is received from the calling modem within the time specified
in S-register S7, the modem hangs up, returns the NO CARRIER result code, and enters
the Idle state.
Any commands following the answer command on the command line are ignored.
This command is aborted if a key is pressed before the answer process is completed, or
when DTR is off, if some options in the &Q or &D commands have been used.
Communication Standard The B command indicates to the modem which special telephone line modulation
Option
standards to use. The modem can be configured to use:
B0
Uses the ITU-T modulation standards for all telephone line data rates. This
includes V.22 for the 1200 bps telephone line data rate and V.21 for the 300
bps telephone line data rate. If S-register S37 is set to 1 (or 2), then V.23 is
used with the originating modem transmitting at 75 bps and receiving at
1200 bps. If S-register S37 is set to any other value, V.23 is not used.
B1
If the 1200 bps telephone line data rate is required, Bell 212A is used
instead of V.22. This is the default value for North America. The 1200 bps
telephone line data rate is required only if:
• S-register S37 is set to 5, or
• S-register S37 is set to 0, and the terminal data rate is 1200 bps.
If the 300 bps telephone line data rate is required, Bell 103 is used instead
of V.21. The 300 bps telephone line data rate is required only if:
• S-register S37 is set to 3, or
• S-register S37 is set to 0 and the terminal data rate is 300 bps.
If neither the 1200 bps nor 300 bps telephone line data rate are required,
then a setting of B1 is ignored and the modem responds as if B0 was set.
B2
Same as B0 for the 1200 bps and 300 bps telephone line date rate. Uses
V.23 with the originating modem transmitting at 1200 bps and receiving at
75 bps, if S-register S37 is set to 1 or 2.
B3
Same as B0 for the 1200 bps and 300 bps telephone line date rate. Uses
V.23 with the originating modem transmitting at 75 bps and receiving at
1200 bps, if S-register S37 is set to 1 or 2.
Data Carrier Detect
&C determines how the modem’s DCD signal relates to the carrier signal from the other
Options
modem. This option occurs only at the beginning of a telephone line connection. If &C is
issued from the Command state, it will not have an immediate effect.
&C0
During asynchronous operation (&Q0 in effect), DCD is on at all times.
During synchronous operation (&Q1), DCD indicates the state of the
carrier signal from the other modem using S-registers S9 and S10. This is
the default value in North America.
&C1
Indicates the state of the carrier signal from the other modem using Sregisters S9 and S10.

Command
Function and Description
D
Dial
&D
Data Terminal Ready
Options
12
The D command causes the modem to dial a telephone call according to the digits and
dial modifiers in the dial string following the command. Any commands following the
dial string on a command line are ignored, unless the semicolon dial modifier is the last
character in the dial string. If the modem is off-hook when the Dial command is given,
the modem dials immediately without trying to detect a dial tone. Characters other than
digits and dial modifiers in a dial string are ignored; however, they are counted as
characters in the command line buffer.
If line current sensing is enabled, and line current is detected before the modem is taken
OFF-HOOK when the modem dials, a NO CARRIER result code is displayed and the
modem enters the IDLE state. If the modem needs not dial (that is, ATD with no dial
string), the modem assumes the call was manually established and attempts to make a
connection.
The D command is not valid when the modem is in the On-Line state.
See “Dial Modifiers and “Modem Result Codes for more information.
&D determines how the modem responds to the DTR signal from the terminal. The
country configuration may prevent the modem from detecting terminal DTR. In this
case, the modem assumes DTR is always on. In North America, terminal DTR is
normally detected. If DTR detection has been prevented, the modem will respond with
an ERROR result to this command.
The response to changes in DTR also depends on the &Q and &D commands. This table
defines what happens when DTR goes off for all possible combinations of the &D and
&Q commands. To see what happens when DTR goes on, refer to the &Q command. The
default value is &D0 in North America:

X
Function and Description
Call Progress
#CID= Caller Id Options
The X command controls whether or not a busy signal or dial tone is detected when
dialing. The X command also limits the result codes the modem returns when dialing.
The operation of the X command is configurable for operation in different countries.
X0
Neither busy signal nor dial tone are detected. When a telephone line
connection is made, the result code does not indicate the telephone line data
rate.
X1
Neither busy signal nor dial tone are detected. When a telephone line
connection is made, the result code indicates the telephone line data rate.
X2
Busy signal is not detected. Dial tone is detected. When a telephone line
connection is made, the result code indicates the telephone line data rate.
X3
Busy signal is detected. Dial tone is not detected. When a telephone line
connection is made, the result code indicates the telephone line data rate.
X4
Both busy signal and dial tone are detected. When a telephone line
connection is made, the result code indicates the telephone line data rate.
This is the default value in North America.
The @ and W dial modifiers are not affected by the X command. The @ dial modifier
may return the result codes 8 (NO ANSWER) or 7 (BUSY) each time it appears in the
dial string. The W dial modifier may return the result codes 6 (NO DIALTONE) or 7
(BUSY) each time it appears in the dial string.
The #CID= command controls how the modem displays
North American caller identification information. The #CID=
command is valid only if the Modem Controller software has
been compiled to support Caller ID. If the software has not
been compiled to support Caller ID then the modem responds
with an ERROR result code to a #CID= command.
Caller Id information is displayed only when it is provided by
the telephone company, and only when the terminal data rate
is 2400 bps. Lower data rates are too slow to display the
Caller Id information.
#CID=0
Do not display caller identification information.
This is the default value.
#CID=1

DIAL MODIFIERS
Dial modifiers perform special functions within a dial command.
Example: [email protected]#71234;<CR>
The example instructs the modem to use tone dialing (T),
to access a number outside a PBX (9), to wait for dial tone
(W), to dial the number 1552368, to do a hook-flash (i.e.
timed break recall), to wait for quiet answer, and to issue
the PBX transfer code #7 before dialing extension number
1234, then to return to the Command state before initiating
the handshake.
Table 3. Dial Modifiers
Modifier
Function
0–9 A B C D # *
Dialing digits and characters. The digits and characters 0-9 A B C D # * specify what numbers the modem
dials. The characters A B C D # * work only when tone dialing is used. The characters are ignored when
pulse dialing is used. The characters A, B, C, and D may be disabled in countries prohibiting their use.
Pulse dialing. P selects the pulse method of dialing. P can be issued within a dial command or as a separate
command. The default method of dialing is Pulse.
Originates a Call in Answer Mode. R makes the modem handshake in answer mode so it can originate a call
to an originate-only modem.
Tone dialing. T selects the tone method of dialing. T can be issued within a dial command or as a separate
command. The default method of dialing is Pulse.
Waits for dial tone. W makes the modem wait for a dial tone before proceeding. If no dial tone is detected the
modem hangs up the telephone line and returns the NO DIALTONE result code.
Delays Processing of Next Character. A comma (,) makes the modem pause for the length of time in Sregister S8 before processing the next character in a dial string.
Waits for Quiet Answer. @ makes the modem listen for 5 seconds of silence before continuing. The modem
will wait up to the length of time in S-register S7. If 5 seconds (configurable by country) of silence are not
detected within the time period in S-register S7, the modem hangs up and returns the NO ANSWER result
code. If 5 seconds of silence are detected, the modem continues processing the other characters in the dial
string.
Timed Break Recall (Hookflash). A ! makes the modem hang up the telephone line for the length of time in
S-register S29, then take the telephone line off hook again. This is frequently used to access a PBX’s call
transfer function.
Returns to Command State after dialing. A semicolon (;) tells the modem to return to command state after
dialing without breaking the telephone line connection and without handshaking with the other modem. The
semicolon may only be used when calling a voice mail system that permits tones to transmit numbers when a
connection has been established.

ESCAPE SEQUENCES
An escape sequence is defined as one or more particular
characters sent from the terminal to the modem during the
On-Line state. This sequence is activated to switch the modem to the command state so modem commands may be entered during a telephone line connection. The Escape Sequence characters are typically sent to the other modem as
data.
An escape sequence should not occur accidentally during
an exchange of data between two modems. Unfortunately,
it is impossible to guarantee that any escape sequence will
never occur naturally, because there are no restrictions on
the data or timing between characters sent between two modems during the On-Line state.
The only method of switching from the On-Line state to the
Command state that never occurs naturally during an exchange of data is the Data Terminal Ready signal (the &D1
command). The terminal has complete control of this signal
and it is not part of the data exchanged between the modems.
The Hayes Escape Sequence was adopted by many modem
manufacturers and communication programs before Hayes
was granted a patent for the escape sequence guard times.
Now the unpatented TIME INDEPENDENT ESCAPE SEQUENCE (TIES) has gained popularity with many modem
manufacturers.
TIES Escape Sequence
TIES was developed by a number of modem manufacturers
in response to Hayes enforcing patent rights for their escape
sequence guard time patent.
The Time Independent Escape Sequence, is a sequence of
3 escape characters (+ characters by default). When these
characters are recognized, the modem enters the COMMAND state without sending a confirming result code to the
terminal. The modem then starts a prompt delay timer. From
that point:
‡
‡
‡
If one of the recognized AT commands is received before the timer expires, the timer is stopped, the command
is executed, and its result code is sent to the terminal.
If any other data is received while the timer is running,
the timer is stopped, the modem returns to the On-Line
state, and the received data is sent to the other modem.
If the timer expires, a confirming result code is sent to
the terminal, indicating the modem is in the Command
state.
The escape character and prompt delay timer can be
changed by writing new values to S-registers S2 and S12.
CARRIER DETECTION
After Handshaking, the modem determines if a telephone
line connection exists by detecting the carrier signal from
the other modem. If the carrier is not detected for a long
enough period of time, the modem assumes the telephone
line connection with the other modem has been broken. The
modem uses S-register S9 to determine how long a carrier
must be present before it is detected. The modem uses Sregister S10 to determine how long a carrier is not detected
before the telephone line is hung up.
BLACKLISTING MANAGEMENT
Blacklisting applies separately to each number dialed, and
indicates the call blocking capability for specific phone
numbers. To save Z02205 RAM, calls are treated as if they
are all to the same number.
The first connection attempt after modem reset or a successful connection is always allowed. If a connection attempt is not successful, then each following connection
attempt is checked as follows:
2. If the attempt occurred too quickly (within the intercall timing period) then the attempt is not allowed,
Modem Result Code indicates the call is DELAYED.
3. If there is a blacklisting period limiting the number of
attempts that may be made within the period, and too
many attempts have been made, then the attempt is not
allowed, Modem Result Code indicates the call is
either DELAYED (if a call may be made later), or
BLACKLISTED (if no call may be made later).
1. If voice answer was detected too many times the
attempt is not allowed, Modem Result Code indicates
the call is BLACKLISTED.

DYNAMIC POWER MANAGEMENT
The Z02205 incorporates a low-power SLEEP mode. In this
mode, the clock is shut down (effectively stopping the part).
The Modem Controller software automatically puts the modem’s data pump into a power-saving SLEEP mode when it
is not used and there is no connection. The Modem Controller software also puts the Modem Controller to sleep
when possible. This power-saving feature reduces the
amount of current used by 8 mA.
This sleep feature operates transparently to the modem’s operation, saving approximately 58 mA of power when both
the modem data pump and controller are put into sleep
mode.
The modem controller goes to sleep under following conditions:
‡
‡
Looking for an ’A’ (Auto Baud)
The ring line has been debounced
‡
‡
‡
‡
‡
‡
The RINGS register has been cleared
There are no incoming characters
There are no characters in the input queue
The Modem Controller is put to sleep until there is an interrupt, such as:
A start bit from the terminal.
Telephone line ring detection from the telephone line interface.
In SLEEP mode, the modem controller turns off the main
timer interrupt and turns on the ring detect interrupt, leaves
the start bit interrupt running - then halts until an interrupt
occurs.
The Modem Controller cannot sleep if dial blacklisting has
been enabled in the country parameters and is being timed.
Nor can the Modem Controller sleep if AT and D3 is set because a DTR On-to-Off transition can not wake it up
FUNCTIONAL DESCRIPTION
Clock. The Z02205 on-chip oscillator has a high-gain, parallel-resonant amplifier for connection to a crystal (XTAL1
is Input, XTAL2 is Output). The crystal should be AT cut,
16 MHz max., with a series resistance (RS) of less than or
equal to 100 Ohms when counting from 1 MHz to 16 MHz.
Connect the crystal across XTAL1 and XTAL2 using the vendor’s recommended capacitor values from each pin directly
to the device GROUND pin to reduce Ground noise injection
into the oscillator.
Note: For better noise suppression, the capacitors must be tied
directly to the device Ground pin (VSS).
