Microchip Technology 

PIC16F87XA

2.2.2.4 PIE1 Register

The PIE1 register contains the individual enable bits for

the peripheral interrupts.

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 PIC16F873A/876A devices; always maintain this bit clear.

bit 6

ADIE: A/D Converter Interrupt Enable bit

1 = Enables the A/D converter interrupt

0 = Disables the A/D converter interrupt

bit 5

RCIE: USART Receive Interrupt Enable bit

1 = Enables the USART receive interrupt

0 = Disables the USART receive interrupt

bit 4

TXIE: USART Transmit Interrupt Enable bit

1 = Enables the USART transmit interrupt

0 = Disables the USART 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

- 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
