Writing to the WDC register factors the WDC5 bit to be set to “1” (w arm start). If the voltage applied to VCC1 is less
than 4.0 V, either w rite to this register w hen the CPU clock frequency is 2 MHz or w rite tw ice.
The WDC5 bit is set to “0” (cold start) w hen pow er is turned on and can be set to “1” by program only.
