9.3 DMA mode
The ISP1362 also provides the DMA mode for external microprocessors to access
the internal buffer memory of the ISP1362. The DMA operation enables data to be
transferred between the system memory of a microprocessor and the internal buffer
memory of the ISP1362.
Remark:
The DMA operation must be controlled by the DMA controller of the external
microprocessor system (master).
Figure 9
shows the DMA interface between a
microprocessor system and the ISP1362.
The ISP1362 provides two DMA channels. The DMA channel 1 (controlled by the
DREQ1 and DACK1 signals) is for the DMA transfer between the system memory of
a microprocessor and the internal buffer memory of the ISP1362 HC. The DMA
channel 2 (controlled by the DREQ2 and DACK2 signals) is for the DMA transfer
between the system memory of a microprocessor and the internal buffer memory of
the ISP1362 DC. The ISP1362 provides an internal End-Of-Transfer (EOT) signal to
terminate the DMA transfer.
