Note 1: One or more bits in INTSTA, PIR1, PIR2 will be affected (to cause wake-up). 2: When the wake-up is due to an interrupt and the GLINTD bit is cleared, the PC is loaded with the interrupt vector. 3: See Table 5-3 for reset value of specific condition. 4: This is the value that will be in the port output latch. 5: When the device is configured for microprocessor or externded microcontroller mode, the operation of this port does not rely on these registers 6: On any device reset, these pins are configured as inputs. |
