EBDIS: External Bus Disable bit
1 = External system bus disabled, all external bus drivers are mapped as I/O ports
0 = External system bus enabled and I/O ports are disabled
Unimplemented: Read as ‘0’
WAIT<1:0>: Table Reads and Writes Bus Cycle Wait Count bits
11 = Table reads and writes will wait 0 T
10 = Table reads and writes will wait 1 T
01 = Table reads and writes will wait 2 T
00 = Table reads and writes will wait 3 T
Unimplemented: Read as ‘0’
WM<1:0>: TBLWT Operation with 16-bit Bus bits
1x = Word Write mode: LSB and MSB word output, WRH active when MSB written
01 = Byte Select mode: TABLAT data copied on both MS and LS Byte, WRH and (UB or LB)
00 = Byte Write mode: TABLAT data copied on both MS and LS Byte, WRH or WRL will activate
