10.2.3 BOR Controlled by Software
When the BOREN bits of Configuration Word
2 are programmed to ‘01’, the BOR is
controlled by the SBOREN bit. The device woke from Sleep is not delayed by the BOR
Ready condition or the VDD level only when the SBOREN bit is cleared in software
and the device is starting up from a non POR/BOR Reset event.
BOR protection begins as soon as the BOR circuit is ready. The status of the BOR circuit is reflected in the BORRDY bit.
BOR protection is unchanged by Sleep.

11 | X | X | Active | Waits for release of BOR(1) (BORRDY =
1) |
10 | X | Awake | Active | Waits for release of BOR (BORRDY =

| Sleep | Disabled | |||
01 | 1 | X | Active | Waits for BOR Reset release (BORRDY =
1) |
0 | X | Disabled | Begins immediately (BORRDY = x) | |
00 | X | X | Disabled |
Note: TPWRT delay only if the
PWRTS bit field is programmed to a value different from ‘
11’.
