Clock supply to the CPU is stopped
Stopped
Status before STOP mode was set is retained
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
Operation stopped
Operation stopped. However, status before STOP mode was set is retained at voltage higher
than POC detection voltage.
