The reset function is mounted onto all 78K0/Kx2-L microcontroller products.
The following four operations are available to generate a reset signal.
(1) External reset input via RESET pin
(2) Internal reset by watchdog timer program loop detection
(3) Internal reset by comparison of supply voltage and detection voltage of power-on-clear (POC) circuit
(4) Internal reset by comparison of supply voltage of the low-voltage detector (LVI) or input voltage from external
External and internal resets start program execution from the address at 0000H and 0001H when the reset signal
A reset is applied when a low level is input to the RESET pin, the watchdog timer overflows, or by POC and LVI
When a low level is input to the RESET pin, the device is reset. It is released from the reset status when a high
