13.7 Operation of Simplified I
(SCL) and serial data (SDA). This communication function is designed to execute single communication with devices
such as EEPROM, flash memory, and A/D converter, and therefore, can be used only by the master and does not
have a wait detection function. Make sure by using software, as well as operating the control registers, that the AC
specifications of the start and stop conditions are observed.

This is a clocked communication function to communicate with two or more devices by using two lines: serial clock
[Data transmission/reception]
[Interrupt function]
[Error detection flag]
* [Functions not supported by simplified I
Note An ACK is not output when the last data is being received by writing 0 to the SOEmn (SOEm register) bit

• Address field transmission
• Data reception
• Master transmission, master reception (only master function with a single master)
• ACK output function
• Data length of 8 bits
• Manual generation of start condition and stop condition
• Transfer end interrupt
• Overrun error
• Parity error (ACK error)
• Slave transmission, slave reception
• Arbitration loss detection function
• Wait detection function
(When an address is transmitted, the address is specified by the higher 7 bits, and the least significant bit is
used for R/W control.)
