I am interfacing PCF2129 RTC with MIMXRT1020 board using LPSPI in polling mode.I am using LPSPI_MasterTransferBlocking(LPSPI_1_PERIPHERAL, &xTxTransfer) function to read and write data. I can write data but I am facing problem while reading data. Only one data size is mention in this function. 

 I required different data size for transmit data and receive data how can I manage data size for both using LPSPI_MasterTransferBlocking(LPSPI_1_PERIPHERAL, &xTxTransfer)  function?
