PIR1 REGISTER
This register contains the individual flag bits for the
Peripheral interrupts (Figure 4-7).
Note:
These bits will be set by the specified
condition, even if the corresponding
Interrupt Enable bit is cleared (interrupt
disabled) or the GIE bit is cleared (all
interrupts disabled). Before enabling an
interrupt, the user may wish to clear the
corresponding interrupt flag, to ensure that
the program does not immediately branch
to the Peripheral Interrupt service routine.
