C bus (Inter IC) bus mode (supporting multimaster) (
μ
PD784216AY/784218AY Subseries only)
This mode is for communication with devices conforming to the I
2
C bus format.
This mode is for transferring 8-bit data between two or more devices by using two lines: serial clock (SCL0)
and serial data bus (SDA0) lines.
During transmission, a “start condition”, “data”, and “stop condition” can be output onto the serial data bus.
During reception, these data are automatically detected by hardware.
