6.1.1 Limitations on Exiting Stop/Wait Mode
The WDC5 bit in the WDC register determines either cold start-up, power-on reset, or warm start-up, reset
during the microcomputer running. Default value of the WDC5 bit is "0" (cold start-up) when power-on. It is
set to "1" (warm start-up) by writing desired values to the WDC register. The WDC5 bit is not reset,
regardless of a software reset or reset signal input.
Figure 6.7 shows a block diagram of the cold start-up/warm start-up determine function. Figure 6.8 shows
its operation exmaple.

The low voltage detection interrupt is generated and the microcomputer exits stop mode as soon as the
CM10 bit in the CM1 register is set to "1" (all clocks stopped) under the conditions below. Additionally, if
WAIT instruction is executed under these same conditions, the low voltage detection interrupt is immedi-
ately generated and the microcomputer exits wait mode.
- the VC27 bit in the VCR2 register is set to "1" (low voltage detection circuit enabled),
- the D40 bit in the D4INT register is set to "1" (low voltage detection interrupt enabled),
- the D41 bit in the D4INT register is set to "1" (low voltage detection interrupt is used to exit stop/wait
