我用的是CC3200，例程里只有读写8位地址函数，现要实现读取16位地址函数，请问怎么实现。
下面是读8位地址函数：
//****************************************************************************
//
//! Invokes the I2C driver APIs to read from a specified address the device.
//! This assumes the device local address to be of 8-bit. For other
//! combinations use I2CWrite followed by I2CRead.
//!
//! \param ucDevAddr is the 7-bit I2C slave address
//! \param pucWrDataBuf is the pointer to the data to be written (reg addr)
//! \param ucWrLen is the length of data to be written
//! \param pucRdDataBuf is the pointer to the read data to be placed
//! \param ucRdLen is the length of data to be read
//!
//! This function works in a polling mode,
//! 1. Writes the data over I2C (device register address to be read from).
//! 2. In a loop, reads all the bytes over I2C
//!
//! \return 0: Success, < 0: Failure.
//
//****************************************************************************
int
I2C_IF_ReadFrom(unsigned char ucDevAddr,
unsigned char *pucWrDataBuf,
unsigned char ucWrLen,
unsigned char *pucRdDataBuf,
unsigned char ucRdLen)
{
//
// Write the register address to be read from.
// Stop bit implicitly assumed to be 0.
//
RET_IF_ERR(I2C_IF_Write(ucDevAddr,pucWrDataBuf,ucWrLen,0));
//
// Read the specified length of data
//
RET_IF_ERR(I2C_IF_Read(ucDevAddr, pucRdDataBuf, ucRdLen));
return SUCCESS;
}
