TABLE 14-6: INITIALIZATION CONDITIONS FOR ALL REGISTERS (Cont.’d)

WDT Reset

Wake-up via

WDT or

Interrupt

Legend: u = unchanged, x = unknown, - = unimplemented bit, read as '0', q = value depends on condition

Note 1: One or more bits in INTCON and/or PIR1 will be affected (to cause wake-up).

2: When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector

(0004h).

3: See Table 14-5 for reset value for speciﬁc condition.

4: Bits PIE1<6> and PIR1<6> are reserved on the PIC16C923, always maintain these bits clear.

5: PORTA values when read.
