18.3 Control

The following registers are used to control the serial bus interface and monitor the operation status.

• Serial bus interface control register 1 (SBI0CR1)

• Serial bus interface control register 2 (SBI0CR2)

• Serial bus interface status register 2 (SBI0SR2)

• Serial bus interface data buffer register (SBI0DBR)

•I2C bus address register (I2C0AR)

In addition, the serial bus interface has low power consumption registers that save power when the serial bus inter-

face is not being used.

Note 1: When SBI0EN is cleared to "0", the clock supply to the serial bus interface is stopped. At this time, the data written

to the serial bus interface control registers is invalid. When the serial bus interface is used, set SBI0EN to "1" and

then write the data to the serial bus interface control registers.
