3.9.1 DTACK Signal Description
The DTACK signal is the external input data acknowledge signal. When using the external DTACK signal as a
data acknowledge signal, the bus time-out monitor generates a bus error when a bus cycle is not terminated by the
external DTACK signal after 1022 HCLK counts have elapsed. Only the CS5 group supports DTACK signal
function when the external DTACK signal is used for data acknowledgement.
3.9.2 DTACK Signal Timing
Figure 6 through Figure 9 show the access cycle timing used by chip-select 5. The signal values and units of
measure for this figure are found in the associated tables.
