PIC16F7X7
2.2.2.4
PIE1 Register
Note:
Bit PEIE (INTCON<6>) must be set to
enable any peripheral interrupt.
The PIE1 register contains the individual enable bits for
the peripheral interrupts.

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.

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