MCLRE: MCLR Pin Enable bit⁽¹⁾
1 = MCLR pin enabled; RA5 input pin disabled
0 = RA5 input pin enabled; MCLR disabled
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
Unimplemented: Read as ‘0’
PWRTEN: Power-up Timer Enable bit
0 = PWRT disabled
1 = PWRT enabled
Unimplemented: Read as ‘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 VPP-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.
