Memory map/register definition
21.3.1 Control Register (DMA_CR)
The CR defines the basic operating configuration of the DMA.
Arbitration can be configured to use either a fixed-priority or a round-robin scheme. For
fixed-priority arbitration, the highest priority channel requesting service is selected to
execute. The channel priority registers assign the priorities; see the DCHPRIn registers.
For round-robin arbitration, the channel priorities are ignored and channels are cycled
through without regard to priority.
Address: DMA_CR is 4000_8000h base + 0h offset = 4000_8000h

For proper operation, writes to the CR register must be
performed only when the DMA channels are inactive; that is,
when TCDn_CSR[ACTIVE] bits are cleared.
This read-only field is reserved and always has the value zero.
