MAXCNT0: Channel Base Address + 0x0020 - Read/Write
MAXCNT1: Channel Base Address + 0x0030 - Read/Write
x = “0” or “1”. Maximum byte count for the buffer. Represents the double buffer
per channel. Only the low order 16 bits are used. Each MAXCNTx register
must be programmed before it’s corresponding BASEx register.

Maximum byte count for the buffer.
x = “0” or “1”. Base address for the current and next DMA
transfer. Loaded with start address after enabling the DMA
Channel, the latter event required to take the Channel
State machine into the STALL state, the former event
required to enter the ON State.
