microprocessor must still issue a RD or WR signal to ISP1161’s RD or WR pin.
(DACK Only mode does not need the RD or WR signal.) ISP1161 will repeat the DMA
cycles until it receives an EOT signal to terminate the DMA transfer.
ISP1161 supports both external EOT and internal EOT signals. The external EOT
signal is received as input from ISP1161’s EOT pin: it generally comes from the
external microprocessor. The internal EOT signal is generated by ISP1161 internally.
To select either, set the DMA configuration registers. For example, for the HC, setting
bit 2 of the HcDMAConfiguration register (21H - Read, A1H - Write) to 1 will enable
the DMA counter for DMA transfer. When the DMA counter reaches the value of
HcTransferCounter register, the internal EOT signal will be generated to terminate the
DMA transfer.
ISP1161 supports either single-cycle burst mode DMA operation or multiple-cycle
burst mode DMA operation.
In both figures, the DMA transfer is configured such that DREQ is active HIGH and
DACK is active LOW.
N = 1/2 byte count of transfer data.
