NOTE:
1. If the DSD bit in the DMiCON register is "0" (fixed), this register can only be written to when the DMAE bit in the
DMiCON register is "0" (DMA disabled). If the DSD bit is set to "1" (forward direction), this register can be written to
at any time. If the DSD bit is set to "1" and the DMAE bit is "1" (DMA enabled), the DMAi forward address pointer
can be read from this register. Otherwise, the value written to it can be read.

NOTE:
1. If the DAD bit in the DMiCON register is "0" (fixed), this register can only be written to when the DMAE bit in the
DMiCON register is "0"(DMA disabled). If the DAD bit is set to "1" (forward direction), this register can be written to at
any time. If the DAD bit is set to "1" and the DMAE bit is "1" (DMA enabled), the DMAi forward address pointer can
be read from this register. Otherwise, the value written to it can be read.

Set the transfer count minus 1. The written value is
stored in the DMAi transfer counter reload register, and
when the DMAE bit in the DMiCON register is set to "1"
(DMA enabled) or the DMAi transfer counter
underflows when the DMASL bit in the DMiCON
register is "1" (repeat transfer), the value of the DMAi
transfer counter reload register is transferred to the
DMAi transfer counter. When read, the DMAi transfer
counter is read.
