2.2.2.7

PIR2 Register

Note:

Interrupt flag bits are set when an interrupt

condition occurs regardless of the state of

its corresponding enable bit, or the global

enable bit, GIE (INTCON<7>). User

software should ensure the appropriate

interrupt flag bits are clear prior to

enabling an interrupt.

The PIR2 register contains the flag bit for the EEPROM

write operation interrupt.
