6.3
A reset has priority over any other exception. When the RES pin goes low, all processing halts and
this LSI enters the reset state. To ensure that this LSI is reset, hold the RES pin low for at least 20
ms with the STBY pin driven high when the power is turned on. When operation is in progress,
hold the RES pin low for at least 20 states.
The chip can also be reset by the overflow that is generated in watchdog timer mode of the
watchdog timer. For details, see section 28, Power-Down Modes, and section 18, Watchdog Timer
(WDT).
A reset initializes the internal state of the CPU and the registers of the on-chip peripheral modules.
The interrupt control mode is 0 immediately after a reset.
6.3.1
When the RES pin goes high after being held low for the necessary time, this LSI starts reset
exception handling as follows:
1. The internal state of the CPU and the registers of the on-chip peripheral modules are
2. The reset exception handling vector address is read and transferred to the PC, and program
Figures 6.1 and 6.2 show examples of the reset sequence.
