PIC16F870/871
3.10
The configuration word contains a bit that write protects
the FLASH program memory, called WRT. This bit can
only
PIC16F870/871 devices via ICSP. Once write protec-
tion 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 program memory reads.
