DMRBCT is a register used to set the number for reloading to the DMA current byte count
register (DMCBCTn).
To enable reloading, set the DMA byte count reload function enable bit (BRLOD) in the DMA
control register A (DMCNTAn) to 1. In this case, set both the DMA current byte count register
(DMCBTn) and DMA reload byte count address register (DMRBCTn).
Note: Set this register so that DMA transfer is performed within the correctly aligned address

When the transfer size is set to 16 bits (SZSEL = "001"): (b0) = "0".
When the transfer size is set to 32 bits (SZSEL = "010"): (b1, b0) = (0, 0).
