u = unchanged, x = unknown, — = unimplemented bit, reads as ‘0’, q = value depends on condition.
If V
One or more bits in INTCON and/or PIR1 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.
If Reset was due to brown-out, then bit 0 = 0. All other Resets will cause bit 0 = u.
Accessible only when SSPM<3:0> = 1001.
DD
goes too low, Power-on Reset will be activated and registers will be affected differently.
