PIC12F683
12.1
The configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’) to select various
device configurations as shown in Register 12-1.
These bits are mapped in program memory location
2007h.

1 = Fail-Safe Clock Monitor is enabled
0 = Fail-Safe Clock Monitor is disabled
IESO: Internal External Switchover bit
1 = Internal External Switchover mode is enabled
0 = Internal External Switchover mode is disabled
BODEN<1:0>: Brown-out Detect Selection bits
11 = BOD enabled
