MCLRE: MCLR Pin Enable bit⁽²⁾
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⁽³⁾
11 = Brown-out Reset set to lowest voltage
10 = Brown-out Reset
01 = Brown-out Reset set to highest voltage
00 = Downside protection on POR is enabled – “zero-power” is selected

1 = Default location for SCL1/SDA1 pins
0 = Alternate location for SCL1/SDA1 pins
PWRTEN: Power-up Timer Enable bit
1 = PWRT is enabled
0 = PWRT is disabled
LVRCFG: Low-Voltage Regulator Configuration bit⁽¹⁾
1 = Low-voltage regulator is not available
0 = Low-voltage regulator is available and controlled by the LVREN bit (RCON<12>) during Sleep
BOREN<1:0>: Brown-out Reset Enable bits
11 = Brown-out Reset is enabled in hardware; SBOREN bit is disabled
10 = Brown-out Reset is enabled only while device is active and disabled in Sleep; SBOREN bit is disabled
01 = Brown-out Reset is controlled with the SBOREN bit setting
00 = Brown-out Reset is disabled in hardware; SBOREN bit is disabled
Note 1:

3:
This setting only applies to the “FV” devices. This bit is reserved and should be maintained as ‘1’ on “F”
devices.
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 Section 29.0 “Electrical Characteristics” for BOR voltages.
