<SIOE>: It specifies SIO operation. When SIO is to be used, be sure to enable SIO by setting "1" to this register before
setting any other registers of the SIO module. When SIO operation is disabled, the clock will not be supplied to the SIO
module except for the register part and thus power consumption can be reduced. If SIO is enabled once and then
disabled, any register setting is maintained.
