TABLE 6-1:

RESET FLAG BIT OPERATION

bit 2

IDLE: Wake-up From Idle Flag bit

= Device has been in Idle mode

= Device has not been in Idle mode

bit 1

BOR: Brown-out Reset Flag bit

= A Brown-out Reset has occurred

Note that BOR is also set after a Power-on Reset.

= A Brown-out Reset has not occurred

bit 0

POR: Power-on Reset Flag bit

= A Power-on Reset has occurred

= A Power-on Reset has not occurred

RCON: RESET CONTROL REGISTER(1) (CONTINUED)

Note 1: All of the Reset status bits may be set or cleared in software. Setting one of these bits in software does not

cause a device Reset.

2: If the FWDTEN Configuration bit is ‘1’ (unprogrammed), the WDT is always enabled, regardless of the

SWDTEN bit setting.

3: Re-enabling the regulator after it enters Standby mode will add a delay, TVREG, when waking up from

Sleep. Applications that do not use the voltage regulator should set this bit to prevent this delay from

occurring.
