Universal Serial Bus Series Microcontroller

R3 [2] Zero flag. It will be set to 1 when the result of an arithmetic or logic operation is zero.

R3 [3] Power down flag. It will be set to 1 during Power-on phase or by “WDTC” command and cleared when the MCU enters into Power down mode. It remains in its previous state after a Watchdog Reset.

0: Power down

1: Power-on

R3 [4] Time-out flag. It will be set to 1 during Power-on phase or by “WDTC” command. It is reset to 0 by WDT time-out.

0: Watchdog timer overflow occurs

1: No Watchdog timer overflow

The various states of Power down flag and Time-out flag at different conditions are shown below:
