• If a DMAC transfer cycle occurs immediately after a DMAC register read cycle, the DMAC
(2)
When the MSTP13 bit in MSTPCRH is set to 1, the DMAC clock stops, and the module stop state
is entered. However, 1 cannot be written to the MSTP13 bit if any of the DMAC channels is
enabled. This setting should therefore be made when DMAC operation is stopped.
When the DMAC clock stops, DMAC register accesses can no longer be made. Since the
following DMAC register settings are valid even in the module stop state, they should be
invalidated, if necessary, before a module stop.
