I am using spi 1 of kinetis k70 (connected to spi nor)
I am trying to read manufacturer id of spi nor ,
For this i have to write "9f" to spi nor and it will written manufacturer id ,but i am able to read the data
I have used the example given in help
and used spi and consoleio components from processor expert

#define BLOCK_SIZE 4
uint8_t OutData[BLOCK_SIZE] = "9F";
uint8_t InpData[BLOCK_SIZE];
volatile LDD_SPIMASTER_TError ComError = 0U;
LDD_TError Error;
LDD_TDeviceData *MySPIPtr;
int main(void)

MySPIPtr = SM1_Init(NULL); /* Initialization of SM1 component */
while(1){
SM1_SelectConfiguration(MySPIPtr, 1U, 1U); /* Select chip select 0 and attribute set 0 */
Error = SM1_ReceiveBlock(MySPIPtr, InpData, BLOCK_SIZE); /* Request data block reception */
printf("Receive --> %x\n",InpData);
Error = SM1_SendBlock(MySPIPtr, OutData, BLOCK_SIZE); /* Start transmission/reception */
while (!SM1_GetBlockReceivedStatus(MySPIPtr)) { /* Wait until data block is transmitted/received */
SM1_Main(MySPIPtr);
}
}

So when i print i get Receive --> 1fff00d8
which is some wrong value ,ii think i am not reading correctly,what should i change in the program to do it
