3.5
In the initial state of this LSI, some of on-chip modules are set in module standby state for saving
power. When operating these modules, clear module standby state according to the procedure in
section 19, Power-Down Modes.
3.6
When changing operating mode while power is applied to this LSI, make sure to do it in the
power-on reset state (that is, the low level is applied to the RES pin).
