In block transfer mode, the bus is released every time a 1-block size of transfers at a single transfer
request is completed.
In figure 7.28, the TEND signal output is enabled and data is transferred in words from the
external 16-bit 2-state access space to the external 16-bit 2-state access space in block transfer
mode.
