Function:
void WFSpiTxRx(void)
Summary:
Transmits and receives SPI bytes
Description:
Transmits and receives N bytes of SPI data.
Precondition:
None
Parameters:
p_txBuf - pointer to SPI tx data
txLen - number of bytes to Tx
p_rxBuf - pointer to where SPI rx data will be stored
rxLen - number of SPI rx bytes caller wants copied to p_rxBuf
Returns:
None
Remarks:
Will clock out the larger of txLen or rxLen, and pad if necessary.
