Introduction
This Master application demonstrates the data transfer in master mode with performance measurment.
- McSPI is configured in Tx Only mode with FIFO enabled for Tx.
- Word Length tested is 8 bits.
- SPI CLK Frequency used is 12 MHZ.
- Number of Words is 5.
- Data is transmitted on D0 pin.
- Data transmission is in polled mode.
To modify the example to use main domain SPI, refer Accessing main and wakeup domain peripherals from MCU domain
