MCLRE: MCLR Pin Enable bit⁽¹⁾
1 = MCLR pin is enabled; RA5 input pin is disabled
0 = RA5 input pin is enabled; MCLR is disabled
BORV<1:0>: Brown-out Reset Enable bits⁽²⁾
11 = Brown-out Reset is set to the low trip point
10 = Brown-out Reset is set to the middle trip point
01 = Brown-out Reset is set to the high trip point
00 = Downside protection on POR is enabled (Low-Power BOR is selected)
I2C1SEL: Alternate MSSP1 I²C™ Pin Mapping bit⁽³⁾
1 = Default location for SCL1/SDA1 pins (RB8 and RB9)
0 = Alternate location for SCL1/SDA1 pins (ASCL1/RB6 and ASDA1/RB5)
PWRTEN: Power-up Timer Enable bit
1 = PWRT is enabled
0 = PWRT is disabled
Unimplemented: Read as ‘0’
BOREN<1:0>: Brown-out Reset Enable bits
11 = BOR is enabled in hardware; SBOREN bit is disabled
10 = BOR is enabled only while device is active and disabled in Sleep; SBOREN bit is disabled
01 = BOR is controlled with the SBOREN bit setting
00 = BOR is disabled in hardware; SBOREN bit is disabled
Note 1:

3:
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.
Refer to Table 26-5 for BOR trip point voltages.
Implemented in 28-pin devices only. This bit position must be programmed (= 1) in all other devices for I²C
functionality to be available.
