PIC16(L)F1826/1827
9. Module: BOR
9.1 BOR Reset
DS80485G-page 8
This issue affects only the PIC16LF1826/1827
devices. The device may undergo a BOR Reset
when waking-up from Sleep and BOR is re-
enabled. A BOR Reset may also occur the
moment the software BOR is enabled.
Under certain voltage and temperature conditions
and when either SBODEN or BOR_NSLEEP is
selected, the devices may occasionally reset when
waking-up from Sleep or BOR is enabled.
Work around
Method 1: In applications where BOR use is
Method 2: Set the FVREN bit of the

bit on at all times.
only during run-time, use the
software-enabled BOR by setting
the SBODEN option on the
Configuration Word. BOR should
be turned off by software before
Sleep, then follow the below
sequence for turning BOR on
after Wake-up:
as described in Method 3, but use
the following sequence:
a. Switch to internal 32 kHz
b. Upon wake-up, turn on FVR
c. Manually turn on the BOR;
d. Switch the clock back to the

enabling BOR for the first time during
program execution.
