WAIT: External Bus Wait Enable bit⁽¹⁾
1 = Wait states for operations on external memory bus disabled
0 = Wait states for operations on external memory bus enabled
BW: Data Bus Width Select bit⁽¹⁾
1 = 16-bit External Bus mode
0 = 8-bit External Bus mode
EMB1:EMB0: External Memory Bus Configuration bits⁽¹⁾
11 = Extended Microcontroller mode, 20-bit Address mode
10 = Extended Microcontroller mode,16-bit Address mode
01 = Extended Microcontroller mode,12-bit Address mode
00 = Microcontroller mode – external bus disabled
EASHFT: External Address Bus Shift Enable bit⁽¹⁾
1 = Address shifting enabled; address on external bus is offset to start at 000000h
0 = Address shifting disabled; address on external bus reflects the PC value
Unimplemented: Read as ‘0’
Note 1: Implemented only on 80-pin devices.
Legend:
R = Readable bit
WO = Write-once bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared
