PIC16F870/871
2.2.2.7
The PIR2 register contains the flag bit for the EEPROM
write operation interrupt.
.
REGISTER 2-7:
DS30569B-page 22
Note:
bit 7-5
bit 4
bit 3-0
Interrupt flag bits get set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User soft-
ware should ensure the appropriate inter-
rupt flag bits are clear prior to enabling an
interrupt.

bit 7
Unimplemented: Read as '0'
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = The write operation completed (must be cleared in software)
0 = The write operation is not complete or has not been started
Unimplemented: Read as '0'
