Note 1: If VDD goes too low, Power-on Reset will be activated and registers will be affected differently. 2: One or more bits in INTCON and/or PIR1 will be affected (to cause wake-up). 3: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h). 4: See Table 12-5 for Reset value for specific condition. 5: If Reset was due to brown-out, then bit 0 = 0. All other Resets will cause bit 0 = u. |
