13.4.1 Stopping the operation by units
is 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
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
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.

If SAUmEN = 0, writing to a control register of serial array unit m is ignored, and, even if the
register is read, only the default value is read (except for input switch control register (ISC),
noise filter enable register (NFEN0), port input mode registers (PIM0, PIM4, PIM9, PIM12,
PIM14), port output mode registers (POM0, POM4, POM9, POM12, POM14), port mode
registers (PM0, PM1, PM4, PM9, PM12, PM14), and port registers (P0, P1, P4, P9, P12, P14)).
