Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 MCLRE: MCLR
Pin Enable bit
(1)
1 = MCLR pin enabled; RA5 input pin disabled
0 = RA5 input pin enabled; MCLR
disabled
bit 6-5 BORV<1:0>: Brown-out Reset Enable bits
(2)
11 = Brown-out Reset set to lowest voltage
10 = Brown-out Reset
01 = Brown-out Reset set to highest voltage
00 = Low-power Brown-out Reset occurs around 2.0V
bit 4 Unimplemented: Read as ‘0’
bit 3 PWRTEN: Power-up Timer Enable bit
0 = PWRT disabled
1 = PWRT enabled
bit 2 Unimplemented: Read as ‘0’
bit 1-0 BOREN<1:0>: Brown-out Reset Enable bits
11 = Brown-out Reset enabled in hardware; SBOREN bit disabled
10 = Brown-out Reset enabled only while device is active and disabled in Sleep; SBOREN bit disabled
01 = Brown-out Reset controlled with the SBOREN bit setting
00 = Brown-out Reset disabled in hardware; SBOREN bit disabled
Note 1: The MCLRE fuse can only be changed when using the V
PP-Based ICSP™ mode entry. This prevents a
user from accidentally locking out the device from the low-voltage test entry.
2: Refer to the electrical specifications for BOR voltages.
