The circuit mentioned above results in a slower data transfer with the HSCX. HSCX usually
performs block transfers. The block length is up to 32 bytes. The DMA request line of the IC
remains active as long as more data are needed. Having transmitted the last byte the DMA
request is being reset. Using the additional circuit the DMA request line will be active at least
shortly before T4. So the next DMA cycle will be started four (instead of two) clock cycles later.
Therefore the maximum transmission rate is reduced from 1.25 Mbyte/s to 1.04 Mbyte/s (clock
rate: 12.5 MHz).
For more information refer to
chapter 7.2
(Data Transmission: DMA Mode),
chapter
7.3
(Data
Reception: DMA mode), and Appendix C (Application Example HSCX with 80(C)188 using
DMA).
