Description
Use the modem controller’s Watch-Dog Timer.
This feature enables the Watch-Dog circuitry,
which resets the modem if the modem controller
stops operating successfully. Power fluctuations
or firmware problems can cause the Watch-Dog
Timer to reset the modem to its IDLE state.
When the Watch-Dog Timer is used, the modem
controller is not placed in Sleep mode, regardless
of the setting of MCSLEEP_DISABLE. This
feature is not supported in version 1.2 of the
Z02215.
Do not use the modem’s Watch-Dog Timer.
Output a +5-V signal on Z02215 pin PB2. Use
this parameter to select a country-specific circuit
in a general-purpose DAA.
Output a +0-V signal on Z02215 pin PB2.
Output a +5-V signal on Z02215 pin PB3. Use
this parameter to select a country-specific circuit
in a general-purpose DAA.
Output a +0-V signal on Z02215 pin PB3.
Enable the parallel Line-In-Use detection
method. See the Line-In-Use section for a
description of the two detection methods.
Enable the Serial Line-In-Use detection method.
Use the Z02215 on-chip Active hybrid to cancel
the transmitted signal from the received signal.
Do not use the Z02215 on-chip Active hybrid.
For example, if the DAA contains an Active
hybrid, or if the modem connection is 4 wire.
