bit 7

MCLRE:

MCLR Pin Enable bit(2)

= MCLR pin enabled; RA5 input pin disabled

= RA5 input pin enabled; MCLR disabled

bit 6-5

BORV<1:0>:

Brown-out Reset Enable bits(3)

= Brown-out Reset set to lowest voltage

= Brown-out Reset

= Brown-out Reset set to highest voltage

= Low-power Brown-out Reset occurs around 2.0V

bit 4

I2C1SEL:

Alternate I2C1 Pin Mapping bit(1)

= Alternate location for SCL1/SDA1 pins

= Default location for SCL1/SDA1 pins

bit 3

PWRTEN:

Power-up Timer Enable bit

= PWRT disabled

= PWRT enabled

bit 2

Unimplemented:

Read as ‘0’

bit 1-0

BOREN<1:0>:

Brown-out Reset Enable bits

= Brown-out Reset enabled in hardware; SBOREN bit disabled

= Brown-out Reset enabled only while device is active and disabled in Sleep; SBOREN bit disabled

= Brown-out Reset controlled with the SBOREN bit setting

= Brown-out Reset disabled in hardware; SBOREN bit disabled

Note 1:

Applies only to 28-pin 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 the electrical specifications for BOR voltages.
