bit 7 bit 0

Legend:

R = Readable bit WO = Write-Once bit U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed ‘1’ = Bit is set ‘0’ = Bit is cleared

bit 7 WAIT: External Bus Wait Enable bit

(1)

1 = Wait states for operations on external memory bus is disabled

0 = Wait states for operations on external memory bus is enabled and selected by MEMCON<5:4>

bit 6 BW: Data Bus Width Select bit

(1)

1 = 16-Bit Data Width mode

0 = 8-Bit Data Width mode

bit 5-4 EMB<1:0>: External Memory Bus Configuration bits

(1)

11 = Microcontroller mode, external bus disabled

10 = Extended Microcontroller mode,12-Bit Addressing mode

01 = Extended Microcontroller mode,16-Bit Addressing mode

00 = Extended Microcontroller mode, 20-Bit Addressing mode

bit 3 EASHFT: External Address Bus Shift Enable bit

(1)

1 = Address shifting is enabled; address on external bus is offset to start at 000000h

0 = Address shifting is disabled; address on external bus reflects the PC value

bit 2-0 Unimplemented: Read as ‘0’

Note 1: Implemented on 100-pin devices only.
