I2C0CON is a special function register (SFR) to control transmit and receive operations.

Note:
In the case of a multi-master, check that the I

Initial value
I2C0CON
The I20ST bit is used to control the communication operation of the I
“1”, communication starts. When “1” is overwritten to the I20ST bit in a control register setting wait state after
transmission/reception of acknowledgment, communication starts again.
communication is stopped forcibly.
The I20SP bit is a write-only bit used to request a stop condition. When the I20SP bit is set to “1”, the I
shifts to the stop condition and communication stops. When the I20SP bit is read, “0” is always read.
The I20RS bit is a write-only bit used to request a restart. When this bit is set to “1” during data communication,
the I
only while communication is active (I20ST =“1”). When the I20RS bit is read, “0” is always read.
The I20ACT bit is used to set the acknowledge signal to be output at completion of reception.
The I20ST bit can be set to “1” only when the I2C bus interface is in an operation enable state (I20EN = “1”).
When the I20SP bit is set to “1”, the I20ST bit is set to “0”.
