Functional Description and Application Information
4.4.1
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.
