26.1 Overview
R01UH0042EJ0400 Rev.4.00
Sep 30, 2010
The following reset functions are available.
(1) Four kinds of reset sources
(2) Emergency operation mode
Caution An LVI circuit internal reset does not reset the LVI circuit.
Remark
WDT2 reset signal
• External reset input via the RESET pin
• Reset via the watchdog timer 2 (WDT2) overflow (WDT2RES)
• System reset via the comparison of the low-voltage detector (LVI) supply voltage and detected voltage
• System reset via the detecting clock monitor (CLM) oscillation stop
After a reset is released, the source of the reset can be confirmed with the reset source flag register (RESF).
If the WDT2 overflows during the main clock oscillation stabilization time inserted after reset, a main clock
oscillation anomaly is judged and the CPU starts operating on the internal oscillation clock.
Caution In emergency operation mode, do not access on-chip peripheral I/O registers other than registers

used for interrupts, port function, WDT2, or timer M, each of which can operate with the internal
oscillation clock. In addition, operation of CSIF0 to CSIF4 and UARTC0 using the externally input
clock is also prohibited in this mode.
