4.4
This is a reset generated by the RES pin.
When the RES pin is driven low, all the processing in progress is aborted and the LSI enters a
reset state. In order to firmly reset the LSI, the STBY pin should be set to high and the RES pin
should be held low at least for 20 ms at a power-on. During operation, the RES pin should be held
low at least for 20 states.
4.5
This is an internal reset generated when deep software standby mode is canceled by an interrupt.
When deep software standby mode is canceled, a deep software standby reset is generated, and
simultaneously, clock oscillation starts. After the time specified with DPSWCR has elapsed, the
deep software standby reset is canceled.
For details of the deep software standby reset, see section 24, Power-Down Modes.
4.6
This is an internal reset generated by the watchdog timer.
When the RSTE bit in RSTCSR is set to 1, a watchdog timer reset is generated by a TCNT
overflow. After a certain time, the watchdog timer reset is canceled.
For details of the watchdog timer reset, see section 15, Watchdog Timer (WDT).
4.7
Reading RSTCSR and RSTSR determines which reset was used to execute the reset exception
handling. Figure 4.2 shows an example the flow to identify a reset generation source.
