14.4.1 Stopping the operation by units
not used is stopped in order to reduce the power consumption and noise.

Each serial interface of serial array unit has the operation stop mode.
In this mode, serial communication cannot be executed, thus reducing the power consumption.
In addition, the P10/SCK20/SCL20, P11/SI20/SDA20/RxD2/INTP6, P12/SO20/TxD2/TO02, P13/SO10/TxD1/TO04,
The stopping of the operation by units is set by using peripheral enable register 0 (PER0).
PER0 is used to enable or disable use of each peripheral hardware macro. Clock supply to a hardware macro that is
To stop the operation of serial array unit 0, set bit 2 (SAU0EN) to 0.
To stop the operation of serial array unit 1, set bit 3 (SAU1EN) to 0.

Caution If SAUmEN = 0, writing to a control register of serial array unit m is ignored, and, even if the
