5.5 Reset and Wake-up

A RESET can be caused by:

(1) External /RESET pin

(2) Power on reset or Power on voltage detector reset (/POVD reset)

(3) WDT timeout (If enabled and in Green or Normal mode)

Note that only Power on reset or Power on voltage detector reset in Case (2) are

enabled in the system by Code Option bit. If /POVDs are disabled, Power on reset is

selected in Case (2). Refer to Figure 5-9.

Figure 5-9 Block Diagram of Reset of controller

Once RESET occurs, the following functions are performed.



The oscillator is running, or will be started.



The Program Counter (R2) is set to all "0".



When power on, the upper 3 bits of R3 and the upper 2 bits of R4 are cleared.



The Watchdog timer and prescaler are cleared.



The Watchdog timer is disabled.



The CONT register is set to all "1".



The other registers (Bit 7...Bit 0)
