Chip-select assertion can be synchronized with bus control signals to provide output enable, read/write
strobes, or interrupt acknowledge signals. Logic can also generate DSACK signals internally. A single
DSACK generator is shared by all circuits. Multiple chip selects assigned to the same address and con-
trol must have the same number of wait states.
Chip selects can also be synchronized with the ECLK signal available on ADDR23.
When a memory access occurs, chip-select logic compares address space type, address, type of ac-
cess, transfer size, and interrupt priority (in the case of interrupt acknowledge) to parameters stored in
chip-select registers. If all parameters match, the appropriate chip-select signal is asserted. Select sig-
nals are active low. Refer to the following block diagram of a single chip-select circuit.
