9.1.4 I2C MASTER
Following are the functions related to both Single master and multi master I2C.
Note: If you select I2C Interrupt driven communication mode, interrupts must be enabled dur-

ing initialization.
I2C_Init
Void I2C_Init (I2C_Init_Param Init_Value)
Initialization of I2C. By default, I2C peripheral is enabled,
acknowledge and interrupts are disabled. If single master
I2C device is selected, I2C will be idle. You can change
the default configuration by selecting the input parameters
given below. You can pass one or more parameters by
logically ‘OR’ing them.
I2C_DEFAULT_PARAM1
Load all I2C registers with default value. Only I2C periph-
eral is enabled (PE bit is set).
I2C_ENABLE_ACK
Enables acknowledge.
I2C_IT_ENABLE
Enables interrupt
None
1. I/O port should be configured correctly.
2. If you want to configure single master I2C, the ST72F65
device must be selected.
None
1. If you want to enable interrupts, the I2C_IT_ENABLE
parameter has to be passed in the I2C_Init function. After
the I2C_Init function is called, you should use the Ena-
bleInterrupts macro to reset the Interrupt mask.
2. For single master I2C, to configure I2C in master mode,
you have to call I2C_Generate_Start after this function .
