Bit 1—Write Enable 0B (WE0B): Enables or disables writes to all bits in DMACR0B, bits 9, 5,
and 1 in DMABCR, and bit 4 in DMATCR, by the DTC.

Bit 0—Write Enable 0A (WE0A): Enables or disables writes to all bits in DMACR0A, and bits
8, 4, and 0 in DMABCR, by the DTC.

Writes by the DTC to bits 15 to 12 (FAE and SAE) in DMABCR are invalid regardless of the
DMAWER settings. These bits should be changed, if necessary, by CPU processing.
In writes by the DTC to bits 7 to 4 (DTE) in DMABCR, 1 can be written without first reading 0.
To reactivate a channel set to full address mode, write 1 to both Write Enable A and Write Enable
B for the channel to be reactivated.
MAR, IOAR, and ETCR are always write-enabled regardless of the DMAWER settings. When
modifying these registers, the channel for which the modification is to be made should be halted.
