Product data
8.5 FIFO buffer RAM access by DMA mode
The DMA interface between a microprocessor and the ISP1161A1 is shown in
Figure
When doing a DMA transfer, at the beginning of every burst the ISP1161A1 outputs a
DMA request to the microprocessor via the DREQ pin (DREQ1 for HC, DREQ2
for DC). After receiving this signal, the microprocessor will reply with a DMA
acknowledge via the DACK pin (DACK1 for HC, DACK2 for DC), and at the same
time, execute the DMA transfer through the data bus. In the DMA mode, the
microprocessor must issue a read or write signal to the ISP1161A1 RD or WR pin.
The ISP1161A1 will repeat the DMA cycles until it receives an EOT signal to
terminate the DMA transfer.
The ISP1161A1 supports both external and internal EOT signals. The external EOT
signal is received as input on pin EOT, and generally comes from the external
microprocessor. The internal EOT signal is generated by the ISP1161A1 internally.
To select either EOT method, set the appropriate DMA configuration register (see
Section 10.4.2
DMACounterSelect of the HcDMAConfiguration register (21H to read, A1H to write)
to logic 1 will enable the DMA counter for DMA transfer. When the DMA counter
reaches the value of the HcTransferCounter register, the internal EOT signal will be
generated to terminate the DMA transfer.
The ISP1161A1 supports either single-cycle DMA operation or burst mode DMA
operation; see
Fig 17. DMA transfer in single-cycle mode.
