16.3.3 DMA byte count registers 0 to 3 (DBC0 to DBC3)
remaining transfer count during DMA transfer.
412
These 16-bit registers are used to set the byte transfer count for DMA channels n (n = 0 to 3). They store the
These registers can be read or written in 16-bit units.
Remark
If the DBCn register is read during DMA transfer after a terminal count has occurred without the register
being overwritten, the value set immediately before the DMA transfer will be read out (0000H will not be
read, even if DMA transfer has ended).
