Clock supply to the CPU is stopped
Status before HALT mode was set is retained
Operates or stops by external clock input
Operation continues (cannot be stopped)
Set by bits 0 (WDSTBYON) and 4 (WTON) of option byte (000C0H)
• WTON = 0: Stops
• WTON = 1 and WDSTBYON = 1: Oscillates
• WTON = 1 and WDSTBYON = 0: Stops
Operation stopped
Operable in low-current consumption mode
Operation stopped. However, status before HALT mode was set is retained at voltage higher
than POC detection voltage.
Status before HALT mode was set is retained
Operable
Set by bits 0 (WDSTBYON) and 4 (WTON) of option byte (000C0H)
