4.1
There are three types of resets: a pin reset, power-on reset, voltage-monitoring reset, deep software
standby reset, and watchdog timer reset. Table 4.1 shows the reset names and sources.
The internal state and pins are initialized by a reset. Figure 4.1 shows the reset targets to be
initialized.
When using power-on reset and voltage monitoring reset, RES pin must be fixed high.

Source
Voltage input to the RES pin is driven low.
Vcc rises or lowers
Vcc falls (voltage detection: Vdet)
Deep software standby mode is canceled by an
interrupt.
The watchdog timer overflows.
