Transfer mode select bit
0 : Burst transfer mode
1 : Cycle steal transfer mode
Transfer-unit-bit-number select bit
0 : 16 bits
1 : 8 bits
Fix this bit to “0”.
Note: For the DMA3 mode register L, be sure to fix this bit to “0” (2-bus cycle transfer). In this case,
1-bus cycle transfer cannot be used. Additionally, be sure to fix this bit to “0” when either transfer
source or transfer destination is in an internal area. In this case, also, 1-bus cycle transfer
cannot be used.
