11.4 Operation stop mode
P12/SO00/TxD0, P13/TxD3, or P14/RxD3 pin can be used as ordinary port pins in this mode.
11.4.1 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 addition, the P02/SO10/TxD1, P03/SI10/SDA10/RxD1, P04/SCK10/SCL10, P10/SCK00, P11/SI00/RxD0,
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.

Figure 11-22. Peripheral Enable Register 0 (PER0) Setting When Stopping the Operation by Units
Cautions 1. If SAUmEN = 0, writing to a control register of serial array unit m is ignored, and, even if
Remark
(a) Peripheral enable register 0 (PER0) … Set only the bit of SAUm to be stopped to 0.

2. Be sure to clear bits 1 and 6 of PER0 register to 0.
m: Unit number (m = 0, 1),
×: Bits not used with serial array units (depending on the settings of other peripheral functions)
0/1: Set to 0 or 1 depending on the usage of the user
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 register (PIM0), port output
mode register (POM0), port mode registers (PM0, PM1), and port registers (P0, P1)).
