r = reserved, maintain clear. Shaded cells indicate conditions do not apply for the designated device.
One or more bits in INTCON, PIR1 and/or PIR2 will be affected (to cause wake-up).
When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector
(0004h).
See Table 14-5 for Reset value for specific condition.
