(14) Software Reset function
The software Reset function is used to initialize the SBI circuit, when SBI is rocked
by external noises, etc.
An internal Reset signal pulse can be generated by setting SBICR2<SWRST1:0> to
“10” and “01”. This initializes the SBI circuit internally. All command registers and
status registers are initialized as well.
SBICR1<SWRMON>is automatically set to “1” after the SBI circuit has been
initialized.
Note: If the software reset is executied , operation selection is reset, and its mode is set to port mode from I2C
mode.
(15) Serial Bus Interface Data Buffer Register (SBIDBR)
The received data can be read and transferred data can be written by reading or
writing the SBIDBR.
In the master mode, after the start condition is generated the slave address and the
direction bit are set in this register.

CBUS Address Register (I2CAR)
I2CAR<SA6:0> is used to set the slave address when the TMP92CZ26A functions as
a slave device.
The slave address output from the master device is recognized by setting the
I2CAR<ALS> to “0”. The data format is the addressing format. When the slave
address is not recognized at the <ALS> = “1”, the data format is the free data format.
(17) Setting register for IDLE2 mode operation (SBIBR0)
SBIBR0<I2SBI> is the register setting operation/stop during IDLE2-mode.
Therefore, setting <I2SBI> is necessary before the HALT instruction is executed.
