7.1.2
The Peripheral Interrupt Request (PIR) registers con-
tain the individual flag bits for the peripheral interrupts
(Register 7-5). Due to the number of peripheral inter-
rupt sources, there are three Peripheral Interrupt
Request (Flag) registers (PIR1, PIR2, PIR3).
REGISTER 7-4:
DS30475A-page 80
Note 1: Interrupt flag bits are set when an interrupt
2: User software should ensure the appropri-
PIR REGISTERS
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON register).
ate interrupt flag bits are cleared prior to
enabling an interrupt, and after servicing
that interrupt.

7.1.3
The Peripheral Interrupt Enable (PIE) registers contain
the individual enable bits for the peripheral interrupts
(Register 7-5). Due to the number of peripheral inter-
rupt sources, there are three Peripheral Interrupt
Enable registers (PIE1, PIE2, PIE3). When IPEN is
clear, the PEIE bit must be set to enable any of these
peripheral interrupts.
7.1.4
The Interrupt Priority (IPR) registers contain the individ-
ual
(Register 7-7). Due to the number of peripheral inter-
rupt sources, there are three Peripheral Interrupt Prior-
ity registers (IPR1, IPR2, IPR3). The operation of the
priority bits requires that the Interrupt Priority Enable bit
(IPEN) be set.
7.1.5
The Reset Control (RCON) register contains the bit that
is used to enable prioritized interrupts (IPEN).
