Notes:
– For ST72F63B device there is only one address register I2COAR (It does not support 10 bit
– If single master I2C device is selected, I2C will remain idle as in this case I2C can not behave
– When slave is in the interrupt mode. That is,
Caution:
– If ITE bit is forcibly modified in the User routine using the hardware register then the behav-
– If you are using the I2C as both transmitter and receiver, then both should be configured in

By default, Acknowledge and General Call are disabled.
You can change the default configuration by selecting in-
put parameters given below. You can pass one or more
parameters by logically ORing them. I2C peripheral is also
enabled.
I2Cs_DEFAULT_PARAM
Load I2C control registers with default value
I2Cs_ENABLE_ACK
Enables acknowledge.
I2Cs_ENABLE_ENGC
Enables General Call
I2Cs_OAR1Value
Load the OAR1 address.
I2Cs_OAR2Value
Load 10 bit higher address bits and also sets FRi bits ac-
cording to the value of Fcpu.
