/****************************************************************************
               * Function:    BOOL StartTransfer( I2C_MODULE i2c_port, BOOL restart );
               * Summary:     Starts (or restarts) a transfer to/from the EEPROM.
               * Description: This routine starts (or restarts) a transfer to/from the 
               *              EEPROM, waiting (in a blocking loop) until the start (or re-
               *              start) condition has completed.
               *
               * Precondition: The I2C module must have been initialized.
               * Parameters:  restart - If FALSE, send a "Start" condition
               *                      - If TRUE, send a "Restart" condition
               *              i2c_port- I2C1 or I2C2
               * 
               * Returns:     TRUE    - If successful
               *              FALSE   - If a collision occurred during Start signaling
               * Remarks:     This is a blocking routine that waits for the bus to be idle
               *              and the Start (or Restart) sequence to complete.
