I am trying to use the SPIC on PORTC on an xmega32a4u. I have the SPI channel configured as a master. To send data, I chip-select my slave device, write a data byte to the SPI.DATA register, and then wait for the SPI.STATUS register interrupt flag to set.
When I probe the SCK line during transfers, it only strobes high and low once as opposed to continuously pulsing. I have set up the xmega to utilize the internal 32MHz oscillator and have confirmed that the peripheral clock is running at the expected frequency.
Are there any other parameters I may have to configure to run the SPI properly?
