SFR explanation for PIC16F877(3)
PIE1 ( Peripheral Interrupt Enable register ) 8Ch

This register contains the enable bits for various preipheral interrupts.
The value in the parenthesis is in the condition immediately after the turning on.

ADIE : A/D Converter Interrupt Enable bit
1:Enables the A/D converter interrupt
0:Disables the A/D converter interrupt

RCIE : USART Receive Interrupt Enable bit
1:Enable the USART receive interrupt
0:Disable the USART receive interrupt

TXIE : USART Transmit Interrupt Enable bit
1:Enable the USART transmit interrupt
0:Disable the USART transmit interrupt

SSPIE : Synchronous Serial Port(SSP) Interrupt Enable bit
1:Enable the SSP interrupt
0:Disable the SSP interrupt

CCP1IE : CCP1 Interrupt Enable bit
1:Enable the CCP1 interrupt
0:Disable the CCP1 interrupt

TMR2IE : TMR2 to PR2 Match Interrupt Enable bit
1:Enable the TMR2 to PR2 match interrupt
0:Disable the TMR2 to PR2 match interrupt

TMR1IE : TMR1 Overflow Interrupt Enable bit
