Legend:
R = Readable bit
-n = Value at POR
WO = Write-Once bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
bit 6
bit 5-4
bit 3
bit 2-0
WAIT: External Bus Wait Enable bit⁽¹⁾
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⁾
1 = 16-Bit Data Width modes
0 = 8-Bit Data Width modes
EMB<1:0>: External Memory Bus Configuration bits⁽¹⁾
11 = Microcontroller mode, external bus is disabled
10 = Extended Microcontroller mode, 12-bit address width for external bus
01 = Extended Microcontroller mode, 16-bit address width for external bus
00 = Extended Microcontroller mode, 20-bit address width for external bus
EASHFT: External Address Bus Shift Enable bit⁽¹⁾
1 = Address shifting is enabled – external address bus is shifted to start at 000000h
0 = Address shifting is disabled – external address bus reflects the PC value
Unimplemented: Read as ‘0’
Note 1: These bits are implemented on 80-pin devices only.
