Table 10. Stop Mode Recovery Sources and Resulting Action
PS019921-0308
Operating Mode
STOP mode
Stop Mode Recovery Using Watchdog Timer Time-Out
Stop Mode Recovery Using a GPIO Port Pin Transition HALT
Caution:
If the Watchdog Timer times out during STOP mode, the device undergoes a Stop Mode
Recovery sequence. In the Watchdog Timer Control 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! XP F64XX Series devices are configured to respond to interrupts, the eZ8
CPU services the Watchdog Timer 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. On
any GPIO pin 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. The GPIO Stop
Mode Recovery signals are filtered to reject pulses less than 10 ns (typical) in duration. In
the Watchdog Timer Control register, the STOP bit is set to 1.
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. Thus, short puls-
es 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).
In STOP mode, the GPIO Port Input Data registers (PxIN) are disabled. The
