PIC16F87X
4.9
The configuration word contains a bit that write protects
the FLASH program memory, called WRT. This bit can
only be accessed when programming the PIC16F87X
device via ICSP. Once write protection is enabled, only
an erase of the entire device will disable it. When
enabled, write protection prevents any writes to FLASH
program memory. Write protection does not affect pro-
gram memory reads.
