Boot Block Size BBEN BBSIZE End Address of Boot Block Boot Block Size (words) PIC16F15213 PIC16F15223 PIC16F15243 PIC16F15214 PIC16F15224 PIC16F15244 1 xxx – – 0 111 01FFh 512 0 110 03FFh 1024 0 101 07FFh –(6) 2048 0 100 0FFFh –(6) 0 011 1FFFh –(6) 0 010 3FFFh –(6) 0 001 3FFFh –(6) 0 000 3FFFh –(6) Notes: 1. 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. 2. Once protection is enabled through ICSP or a self-write, it can only be reset through a Bulk Erase. 3. Applicable only if SAFEN = 0. 4. Applicable only if BBEN = 0. 5. The 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. 6. 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.
