ETCRB is decremented by 1 after every block transfer, and when the count reaches H'0000 the
DTE bit in DMABCRL is cleared and transfer ends. If the DTIE bit in DMABCRL is set to 1 at
this point, an interrupt request is sent to the CPU or DTC.
Figure 7.15 shows the operation flow in block transfer mode.
