bit 7
EEIE: EE Write Complete Interrupt Enable bit
1 = Enables the EE write complete interrupt
0 = Disables the EE write complete interrupt
ADIE: A/D Converter Interrupt Enable bit (PIC16F676 only)
1 = Enables the A/D converter interrupt
0 = Disables the A/D converter interrupt
Unimplemented: Read as ‘0’
CMIE: Comparator Interrupt Enable bit
1 = Enables the comparator interrupt
0 = Disables the comparator interrupt
Unimplemented: Read as ‘0’
TMR1IE: TMR1 Overflow Interrupt Enable bit
1 = Enables the TMR1 overflow interrupt
0 = Disables the TMR1 overflow interrupt
