3.3 I2C_MasterTransmitter

Function name: I2C_MasterTransmitter(I2CA_BASE, struct I2CHandle *pI2C_Params)

Description: This function can be used to transmit 'N' number of bytes defined in pI2C_Params. This function can be used to perform following EEPROM write operations.

  1. EEPROM byte write

    Set EEPROM.NumOfDataBytes = 1, because one byte needs to be transmitted

  2. EEPROM word write

    Set EEPROM.NumOfDataBytes = 2, because two bytes needs to be transmitted

  3. EEPROM Paged write

    Set EEPROM.NumOfDataBytes = 'N', because 'N' bytes needs to be transmitted - Page size depends upon EEPROM chosen

Below setting applies to all the above EEPROM write operations

Set EEPROM.NumOfAddrBytes = 2, because high address byte and low address byte needs to be transmitted

Arguments:

base : base is the base address of the I2C instance used

pI2C_Params : Pointer to I2C address handle of the slave

Return:Status of I2C transaction
