Description
[7]
EA
Enable All Interrupt
This bit globally enables/disables all interrupts that are individually enabled.
0 = All interrupt sources Disabled.
1 = Each interrupt Enabled depending on its individual mask setting. Individual interrupts will
occur if enabled.
[6]
EADC
Enable ADC Interrupt
0 = ADC interrupt Disabled.
1 = ADC interrupt Enable. When interrupt generated ADCF (ADCCON0.7) set 1.
[5]
EBOD
Enable Brown-Out Interrupt
0 = Brown-out detection interrupt Disabled.
1 = Brown-out detection interrupt Enable. When interrupt generated BOF (BODCON0.3) set 1.
[4]
ES
Enable Serial Port 0 Interrupt
0 = Serial port 0 interrupt Disabled.
1 = Serial port 0 interrupt Enable. When interrupt generated TI (SCON.1) or RI (SCON.0) set 1.
[3]
ET1
Enable Timer 1 Interrupt
0 = Timer 1 interrupt Disabled.
1 = Timer 1 interrupt Enable. When interrupt generated TF1 (TCON.7) set 1.
[2]
EX1
Enable External Interrupt 1
0 = External interrupt 1 Disabled.
1 = External interrupt 1 interrupt Enable. When interrupt generated INT1 pin set 1.
[1]
ET0
Enable Timer 0 Interrupt
0 = Timer 0 interrupt Disabled.
1 = Timer 0 interrupt Enable. When interrupt generated TF0 (TCON.5) set 1.
[0]
EX0
Enable External Interrupt 0
0 = External interrupt 0 Disabled.
1 = External interrupt 0 interrupt Enable. When interrupt generated INT0 pin set 1.
