Section 11 Watchdog Timer (WDT)
11.5.5
Transition to Watchdog Timer Mode or Software Standby Mode
When the WDT operates in watchdog timer mode, a transition to software standby mode is not
made even when the SLEEP instruction is executed when the SSBY bit in SBYCR is set to 1.
Instead, a transition to sleep mode is made.
To transit to software standby mode, the SLEEP instruction must be executed after halting the
WDT (clearing the TME bit to 0).
When the WDT operates in interval timer mode, a transition to software standby mode is made
through execution of the SLEEP instruction when the SSBY bit in SBYCR is set to 1.
