3.2.2 Reset Sources
The MB89630 series of microcontrollers have the following reset sources.
(1) External pin
A Low level is input to the RST pin.
(2) Specification by software
0 is written at the RST bit of the standby-control register.
(3) Power-on
The power is turned on when the power-on reset option is selected.
(4) Watchdog function
The watchdog function is enabled by the watchdog-control register and reaccess to this register is not
obtained within the specified time.
When the stop mode is cleared by reset or power-on reset (option selected), operation is started after
elapse of the oscillation stabilization time.
See the state transition diagram and (d) Reset in 2.1.5 for details of the reset operation.
