PIC16(L)F145X Memory Programming Specification

Microchip Technology 

PIC16(L)F145X

4.3.10 ROW ERASE PROGRAM MEMORY

The Row Erase Program Memory command will erase

an individual row. Refer to Table 4-3 for row sizes of

specific devices and the PC bits used to address them.

If the program memory is code-protected, the Row

Erase Program Memory command will be ignored.

When the address is 8000h-8008h, the Row Erase

Program Memory command will only erase the user ID

locations, regardless of the setting of the CP

Configuration bit.

After receiving the Row Erase Program Memory

command, the erase will not complete until the time

interval, TERAR, has expired.
