Legend:
Note 1: One or more bits in INTCON and/or PIR1 will be affected (to cause wake-up).
1996 Microchip Technology Inc.
2: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt
3: See Table 9-5 for reset value for specific condition.
4: These registers are associated with the Parallel Slave Port and are not implemented on the PIC16C641/642.
