Reset Source
Reset function by RESET pin input
System reset (POCRES) by power-on-clear circuit (POC)
Reset function (WDTRES) by WDT overflow
System reset (LVIRES) by low-voltage detector (LVI)
(2) Reset source flag register 2 (RESF2)
Table 16-1. Values of Bits 0 and 4 of RESF and RESF2 Registers When Reset Source Is Generated
The RESF2 register indicates that a reset signal is generated by the low-voltage detector (LVI).
This register is read-only, in 8-bit units.
This register is cleared to 00H or set to 10H by RESET pin input and the power-on-clear circuit (POC). The
default values are different when a reset is executed by other than these.
Notes 1. After a reset by RESET pin input or the power-on-clear circuit (POC), this register is set to
RESF2
2. Writing 0 to the RESF.LVIRF bit clears (0) the LVIRFS flag.
After reset: Note 1
00H or 10H. After a reset by the low-voltage detector (LVI), this register is set to 01H or 11H.
After a reset by watchdog timer overflow, the register value before reset is held.
