DMAWER is an 8-bit readable/writable register that controls enabling or disabling of writes to
DMACR, DMABCR, and DMATCR by the DTC.
DMAWER is initialized to H'00 by a reset, and in hardware standby mode.
Bits 7 to 4—Reserved: Read-only bits, always read as 0.
Bit 3—Write Enable 1B (WE1B): Enables or disables writes to all bits in DMACR1B, bits 11, 7,
and 3 in DMABCR, and bit 5 in DMATCR, by the DTC.

Bit 2—Write Enable 1A (WE1A): Enables or disables writes to all bits in DMACR1A, and bits
10, 6, and 2 in DMABCR, by the DTC.
