TABLE 4-1: SPECIAL FUNCTION REGISTER SUMMARY (Cont.’d)

Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

Value on

Power-on

Reset

Value on all

other resets

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

shaded locations are unimplemented, read as ‘0’.

Note 1: Registers ADRES, ADCON0, and ADCON1 are not implemented in the PIC16C923, read as '0'.

2: These bits are reserved on the PIC16C923, always maintain these bits clear.

3: These pixels do not display, but can be used as general purpose RAM.

4: PIC16C923 reset values for PORTA: --xx xxxx for a POR, and --uu uuuu for all other resets,

PIC16C924 reset values for PORTA: --0x 0000 when read.

5: Bit1 of ADCON0 is reserved on the PIC16C924, always maintain this bit clear.
