16.6 Software hints
16.6.1 Master mode
The following routine must be executed by the CoolRISC in order to run properly the SPI interface in master mode:
1- Write RegSpiControl to enable the SPI interface and to configure the master mode (configured by default) and
communication settings.
2- Write the data to send in the RegSpiDataOut register. The SpiTxEmpty flag toggles low.
3- Write 1 to the SpiTxEmpty bit to load the shift register with the value inside the RegSpiDataOut register and to
start the byte transmission. The SpiTxEmpty flag toggles back high.
4- Write the next data to send to the RegSpiDataOut register. The SpiTxEmpty flag toggles low.
