Detailed Description

I2C transaction.

This structure defines the nature of the I2C transaction. This structure specifies the buffer and buffer's size that is to be written to or read from the I2C slave peripheral. arg is an optional user supplied argument that will be passed to the callback function when the I2C driver is in I2C_MODE_CALLBACK. nextPtr is to be only used by the I2C driver.
