Note:

The LVP bit cannot be written (to zero) while operating from the LVP programming interface. The purpose of

this rule is to prevent the user from dropping out of LVP mode while programming from LVP mode, or

accidentally eliminating LVP mode from the Configuration state.

Once protection is enabled through ICSP™ or a self-write, it can only be reset through a Bulk Erase.

Applicable only if SAFEN = 0.

Applicable only if BBEN = 0.

BBSIZE[2:0] bits can only be changed when BBEN = 1. Once BBEN = 0, BBSIZE[2:0] can only be changed

through a Bulk Erase.

The maximum Boot Block size is half of the user program memory size. Any selection that will exceed the half

of a device’s program memory will default to a maximum Boot Block size of half PFM. For example, all settings

of BBSIZE from ‘110’ to ‘000’ for a PIC16F15213 (Max PFM = 2048 words) will result in a maximum Boot

Block size of 1024 words.
