Description
Prescaler Select
Selects the clock source input to TCNT of WDT_1.
Controls the operation in power-down mode transition.
0: TCNT counts divided clock of φ-base prescaler (PSM).
1: TCNT counts divided clock of φ
Reset or NMI (REST/NMI)
Selects either a power-on reset or the NMI interrupt
request when TCNT overflows in watchdog timer mode.
0: NMI interrupt is requested.
1: Power-on reset is requested.
When SLEEP instruction is executed in high-speed
mode or medium-speed mode, transition to sleep
mode or software standby mode is made.
(PSS).
When SLEEP instruction is executed in high-speed
mode or medium-speed mode, transition to sleep
mode, software standby mode, or watch mode* is
made.
sure that high-speed mode is set.
