Note 1:
WAIT
U-1
(1)
Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘ 0 ’.
WAIT: External Bus Wait Enable bit
1 = Wait states on the external bus are disabled
0 = Wait states on the external bus are enabled and selected by MEMCON <5:4>
BW: Data Bus Width Select bit
1 = 16-Bit Data Width modes
0 = 8-Bit Data Width modes
ABW<1:0>: External Memory Bus Configuration bits
11 = 8-Bit Address mode (Microcontroller mode)
10 = 12-Bit Address mode
01 = 16-Bit Address mode
00 = 20-Bit Address mode
EASHFT: External Address Bus Shift Enable bit
1 = Address shifting is enabled; external address is shifted to start at 000000h
0 = Address shifting is disabled; external address bus reflects the PC value
Unimplemented: Read as ‘ 0 ’
RTCOSC: RTCC Reference Clock Select bit
1 = RTCC uses SOSC as the reference clock
0 = RTCC uses LF-INTOSC as the reference clock
