1. The CPOL and CPHA bits should both contain the same values for master and slave devices.
Note: Both SPI & I
check the interfaces following an interrupt to determine which one caused the interrupt.

Description
SPI Interrupt bit
Set by MicroConverter at the end of each SPI transfer
Cleared directly by user code or indirectly by reading the SPIDAT SFR
Write Collision Error Bit
Set by MicroConverter if SPIDAT is written to while an SPI transfer is in progress
Cleared by user code
SPI Interface Enable Bit
Set by user code to enable SPI functionality
Cleared by user code to enable standard Port2 functionality
SPI Master/Slave Mode Select Bit
Set by user code to enable Master mode operation (SCLOCK is an output)
Cleared by user code to enable Slave mode operation (SCLOCK is an input)
Clock Polarity Bit
Set by user code to enable SCLOCK idle High
Cleared by user code to enable SCLOCK idle low
Clock Phase Select Bit
Set by user code if leading SCLOCK edge is to transmit data
Cleared by user code if trailing SCLOCK edge is to transmit data.
