Complement set of read functions to be used by the UART ISR and UARTCC3200_read(). Internal use only.
These functions should not be used by the user and are solely intended for the UARTCC3200 driver. The UARTCC3200_FxnSet is a pair of complement functions that are design to operate with one another in a task context and in an ISR context. The readTaskFxn is called by UARTCC3200_read() to drain a circular buffer, whereas the readIsrFxn is used by the UARTCC3200_hwiIntFxn to fill up the circular buffer.
readTaskFxn: Function called by UART read These variables are set and avilalable for use to the readTaskFxn. object->readBuf = buffer; //Pointer to a user buffer object->readSize = size; //Desired no. of bytes to read object->readCount = size; //Remaining no. of bytes to read
readIsrFxn: The required ISR counterpart to readTaskFxn
