chain transfer. When re-setting the control register area, perform masking by setting bits in
DMAWER to prevent modification of the contents of other channels.
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 can always be written to regardless of the DMAWER settings. When
modifying these registers, the channel to be modified should be halted.
