Section 20 Power-Down Modes
20.12.6 Entering Subactive/Watch Mode and DMAC and DTC Module Stop
To enter subactive or watch mode, set DMAC to module stop (write 1 to the MSTPA7 bit) and
reading the MSTPA7 bit as 1 before transiting mode. After transiting from subactive mode to
active mode, clear module stop.
When a DMAC activation source is generated in subactive mode, the DMAC is activated when
module stop is cleared following the transition to active mode.
