7.5.7
In block transfer mode, data transfer is performed with channels A and B used in combination.
Block transfer mode can be specified by setting the FAE bit in DMABCRH and the BLKE bit in
DMACRA to 1. In block transfer mode, a data transfer of the specified block size is carried out in
response to a single transfer request, and this is executed for the number of times specified in
