Section 20 Power-Down State
20.6
20.6.1
The module standby function can halt several of the on-chip supporting modules (the ITU, SCI0,
SCI1, DMAC, refresh controller, and A/D converter) independently of the power-down state. This
standby function is controlled by bits MSTOP5 to MSTOP0 in MSTCR. When one of these bits is
set to 1, the corresponding on-chip supporting module is placed in standby and halts at the
beginning of the next bus cycle after the MSTCR write cycle.
20.6.2
When an on-chip supporting module is in module standby, read/write access to its registers is
disabled. Read access always results in H'FF data. Write access is ignored.
