The DREQ pin will only be driven only after you perform a write access to the DMA Configuration
register (that is, after you have configured the DMA Configuration register).
9.4.4
DMA Hardware register (address: 3Ch)
The DMA Hardware register consists of 1 byte. The bit allocation is shown in
Table 54
.
This register determines the polarity of the bus control signals (EOT, DACK, DREQ,
DIOR and DIOW) and DMA mode (master or slave). It also controls whether the
upper and lower parts of the data bus are swapped (bits ENDIAN[1:0]) for GDMA
(slave) mode.

DIS_XFER_CNT Logic 1 disables the DMA Transfer Counter (see
Table 50
). The
transfer counter can be disabled only in GDMA (slave) mode.

These bits only affect the GDMA slave handshake signals.

00 —
DIOW slave strobes data from the DMA bus into the
ISP1582; DIOR slave puts data from the ISP1582 on the DMA
bus
01 —
DACK slave strobes data from the DMA bus into the
ISP1582; DIOR slave puts data from the ISP1582 on the DMA
bus
10 —
DACK slave strobes data from the DMA bus into the
ISP1582 and also puts data from the ISP1582 on the DMA bus.
(This mode is applicable only to the 16-bit DMA; this mode
cannot be used for the 8-bit DMA.)
