DMAC Byte Counter

In the direct mode, this counter is programmed with the number of bytes

of data to be transferred.

In the command chaining mode, this counter should be loaded by the

processor with the starting address of the list of commands. This register

gets reloaded by the DMAC with the starting address of the current

command. The last command in a list should have bits 0 and 1 set in the

next command pointer.
