As for the cold start-up/warm start-up determine function, the WDC5 flag in the WDC register determines either
cold start-up (reset process) when power-on or warm start-up (reset process) when reset signal is applied 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 WDC bit is not reset, regardless of a software reset or a reset operation.
Figure 6.7 shows Cold Start-up/Warm Start-up Determine Function Block Diagram. Figure 6.8 shows the Cold
Start-up/Warm Start-up Determine Function Operation Example. Figure 6.9 shows WDC Register.
NOTES:
1. The timing of which WDC5 is set is affected by how the RESET signal rises (Time lag between T1 and T2).
