The DREQ pin will be driven only after performing a write access to the DMA Conguration register (that is,
after conguring the DMA Conguration register).
8.4.4 DMA Hardware register (address: 3Ch)
The DMA Hardware register consists of 1 byte. The bit allocation is shown in Table 51.
This register determines the polarity of bus control signals (EOT, DACK, DREQ, DIOR and
DIOW). It also controls whether the upper and lower parts of the data bus are swapped
(bits ENDIAN[1:0]).

MODE[1:0]
Mode: These bits affect GDMA handshake signals.
00 — DIOW strobes data from the DMA bus into the ISP1582; DIOR
puts data from the ISP1582 on the DMA bus.
01 — DACK strobes data from the DMA bus into the ISP1582; DIOR
puts data from the ISP1582 on the DMA bus.
10 — DACK strobes data from the DMA bus into the ISP1582 and
also puts data from the ISP1582 on the DMA bus.
