[Note]
Ÿ
The voltage level supervisor function is only initialized at a reset input pin reset or power-on reset
(POR).
Ÿ
The BRK instruction reset only initializes the CPU if ELEVEL is 2 or higher. Peripheral circuits and other
circuits are not initialized. Use the reset input pin reset or the watchdog timer (WDT) reset to surely
initialize the LSI when an abnormality is detected.
Ÿ
In a BRECON 0-3 reset and SOFTRCON reset, only the corresponding peripheral circuits are initialized.
The CPU and other circuits are not initialized, and not transferred to the system reset mode.
