ACKM<1:0>: Chip Select x Acknowledge Mode bits
11 = Reserved
10 = PMACKx is used to determine when a read/write operation is complete
01 = PMACKx is used to determine when a read/write operation is complete with time-out
00 = PMACKx is not used
AMWAIT<2:0>: Chip Select x Alternate Master Wait States bits
111 = Wait of 10 alternate master cycles
. . .
001 = Wait of 4 alternate master cycles
000 = Wait of 3 alternate master cycles
Unimplemented: Read as ‘0’
DWAITB<1:0>: Chip Select x Data Setup Before Read/Write Strobe Wait States bits
11 = Wait of 3¼ T
