Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
DMA transfer length in bytes.
During configuration, this register contains the DMA transfer length
in bytes. During operation, it contains the last updated value of the
DMA transfer length after being sent to the master interface.
Note: Writing a nonzero value to this register field starts the transfer
if the channel is enabled by setting DMACH1CTL.EN.
