Remark:
The HcTransferCounter register counts the number of bytes even though
the transfer is in number of words. Therefore, the transfer counter should be set to
word_size
×
2. Incorrect setting of the HcTransferCounter register may cause the
ISP1362 to go into an indeterminate state.
The buffer memory access using indirect addressing always starts from the location 0
of each buffer area. Only the front portion of the memory (example:
fi
rst 64 bytes of a
1024 bytes buffer) can be accessed. Therefore, to access a portion of the memory
that does not start from memory location 0, all memory locations before that location
must be accessed in a sequential order. The method is similar to the sequential
fi
le
access method.
9.6 Setting up a DMA transfer
The ISP1362 uses two DMA channels to individually serve the HC and the DC. The
DMA transfer allows the system CPU to work on other tasks while the DMA controller
transfers data to or from the ISP1362. The DMA slave controller, in the ISP1362, is
compatible with the 8327 type DMA controller.
The DMA transfer can be used with the direct addressing mode or the indirect
addressing mode. The registers used in these two modes are shown in
Table 6
.
[1]
In the direct addressing mode, HcTransferCounter must be set to 0001H.

Con
fi
guring registers for a DMA transfer
To set up a DMA transfer, the following HC registers must be con
fi
gured depending
on the type of transfer required:
HcHardwareCon
fi
guration
DREQ1 output polarity (bit 5)
DACK1 input polarity (bit 6)
DACK mode (bit 8).
Hc
μ
PInterruptEnable
If you want an interrupt to be generated after the DMA transfer is complete, set
EOTInterruptEnable (bit 3).
