PIE1 REGISTER

The PIE1 register contains the interrupt enable bits, as

shown in Register 8-2.

Note:

Bit PEIE of the INTCON register must be

set to enable any peripheral interrupt.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

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

SSP1IE: Synchronous Serial Port (MSSP) Interrupt Enable bit

1 = Enables the MSSP interrupt

0 = Disables the MSSP 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 Timer2 to PR2 match interrupt

0 = Disables the Timer2 to PR2 match interrupt

bit 0
