registers for the CPU and LCDC. Regardless of the settings of the bank registers for
program, read and write data of the CPU, the banks to be used as source address memory
and destination address memory are specified individually during DMA operations.
performed by dividing those channels into 2 groups. The DMA channels with the
even-channel number, 0, 2 and 4, are classified into the E-group (ES and ED groups); while
the channels with the odd-channel number, 1 and 3, are classified into the O-group (OS and
OD groups). These registers cannot specify bank numbers for each channel, but specifies
one bank number for all the channels in the same group.
the LOCAL-X area, and also specify bank 2 for storing DMA-destination addresses in the
LOCAL-Y area. If the DMA operation for channel 0 is initiated Assume that the source and
destination addresses specified by the DMA operation, which is described in Section 3.6,
are set into the LOCAL-X and LOCAL-Y areas, respectively. Then, if the DMA operation
for channel 0 is initiated, bank 1 in the LOCAL-X area is configured as the source address
memory, and bank 2 in the LOCAL-Y area is configured as the destination address memory.

The TMP92CF26A supports not only the read and write operations of the CPU, but also
These registers are provided specially for the DMA operation, separately from the bank
The DMAC of the TMP92CF26A supports six channels, and the bank control is
