Description
PDMAC Transfer Count (Default is undefined)
Sets an uncoded 24-bit transfer byte count in 32-bit word units. Also, the
setting of this register must always be a multiple of the transfer size
specified inside the PDMAC Configuration Register. No data transfer is
performed if a count of "0" is set.
This byte count value is calculated from the transferred byte size as the
PDMAC performs a DMA transfer.
This register value is held without being affected by a Reset.
