Table 10. Stop Mode Recovery Sources and Resulting Action
PS025111-1207
Operating Mode
STOP mode
Caution:
Stop Mode Recovery using WDT Time-Out
Stop Mode Recovery using GPIO Port Pin Transition
register is set to 1.
The following sections provide more detailed information about each of the Stop Mode
Recovery sources.
If the Watchdog Timer times out during STOP mode, the device undergoes a Stop Mode
Recovery sequence. In the reset status (RSTSTAT) register, the WDT and STOP bits are
set to 1. If the Watchdog Timer is configured to generate an interrupt upon time-out and
the Z8 Encore!
services the WDT interrupt request following the normal Stop Mode Recovery sequence.
Each of the GPIO port pins may be configured as a Stop Mode Recovery input source. If
any GPIO pin is enabled as a Stop Mode Recovery source, a change in the input pin value
(from high to low or from low to high) initiates Stop Mode Recovery. In the reset status
(RSTSTAT) register, the STOP bit is set to 1.
In STOP mode, the GPIO port input data registers (PxIN) are disabled. The port input
data registers record the port transition only if the signal stays on the port pin through
the end of the Stop Mode Recovery delay. As a result, short pulses on the port pin can
initiate Stop Mode Recovery without being written to the port input data register or
without initiating an interrupt (if enabled for that pin).
