PEIF
PEIF: Peripheral Interrupt Flag bit
This bit is the OR of all peripheral interrupt flag bits AND’ed with their corresponding enable bits.
1 = A peripheral interrupt is pending
0 = No peripheral interrupt is pending
T0CKIF: External Interrupt on T0CKI Pin Flag bit
This bit is cleared by hardware, when the interrupt logic forces program execution to vector (18h).
1 = The software specified edge occurred on the RA1/T0CKI pin
0 = The software specified edge did not occur on the RA1/T0CKI pin
T0IF: TMR0 Overflow Interrupt Flag bit
This bit is cleared by hardware, when the interrupt logic forces program execution to vector (10h).
1 = TMR0 overflowed
0 = TMR0 did not overflow
INTF: External Interrupt on INT Pin Flag bit
This bit is cleared by hardware, when the interrupt logic forces program execution to vector (08h).
1 = The software specified edge occurred on the RA0/INT pin
0 = The software specified edge did not occur on the RA0/INT pin
PEIE: Peripheral Interrupt Enable bit
This bit enables all peripheral interrupts that have their corresponding enable bits set.
1 = Enable peripheral interrupts
0 = Disable peripheral interrupts
T0CKIE: External Interrupt on T0CKI Pin Enable bit
1 = Enable software specified edge interrupt on the RA1/T0CKI pin
0 = Disable interrupt on the RA1/T0CKI pin
T0IE: TMR0 Overflow Interrupt Enable bit
1 = Enable TMR0 overflow interrupt
0 = Disable TMR0 overflow interrupt
INTE: External Interrupt on RA0/INT Pin Enable bit
1 = Enable software specified edge interrupt on the RA0/INT pin
0 = Disable software specified edge interrupt on the RA0/INT pin
