PIE1 Register
The PIE1 register contains the individual enable bits for
the peripheral interrupts.
REGISTER 2-4:
PIE1: PERIPHERAL INTERRUPT ENABLE REGISTER 1 (ADDRESS 8Ch)
Note:
Bit PEIE (INTCON<6>) must be set to
enable any peripheral interrupt.

PSPIE: Parallel Slave Port Read/Write Interrupt Enable bit(1)
1
= Enables the PSP read/write interrupt
0
= Disables the PSP read/write interrupt
Note 1: PSPIE is reserved on 28-pin devices; always maintain this bit clear.

1
= Enables the A/D converter interrupt
0
= Disables the A/D converter interrupt
bit 5
RCIE: AUSART Receive Interrupt Enable bit
1
= Enables the AUSART receive interrupt
0
= Disables the AUSART receive interrupt
bit 4
TXIE: AUSART Transmit Interrupt Enable bit
1
= Enables the AUSART transmit interrupt
0
= Disables the AUSART transmit interrupt
bit 3
SSPIE: Synchronous Serial Port Interrupt Enable bit
1
= Enables the SSP interrupt
0
= Disables the SSP interrupt
bit 2
CCP1IE: CCP1 Interrupt Enable bit
1
= Enables the CCP1 interrupt
0
= Disables the CCP1 interrupt
bit 1
TMR2IE: TMR2 to PR2 Match Interrupt Enable bit
1
= Enables the TMR2 to PR2 match interrupt
0
= Disables the TMR2 to PR2 match interrupt
bit 0
TMR1IE: TMR1 Overflow Interrupt Enable bit
1
= Enables the TMR1 overflow interrupt
0
= Disables the TMR1 overflow interrupt
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
