reset processing. A reset by the watchdog timer is automatically released, and program execution starts using the

execution starts using the internal high-speed oscillation clock (see CHAPTER 23 POWER-ON-CLEAR CIRCUIT
and CHAPTER 24 LOW-VOLTAGE DETECTOR) after reset processing.
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 and detection voltage of low-power-supply detector (LVI)
External and internal resets have no functional differences. In both cases, program execution starts at the address
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
