11. C8051
The C8051.c module contains all the low level, 8051 dependent functions. The code mostly comprises of hardware
SPI setup and SPI read/write function calls.
The SetHwMasterSpi() function initializes the 3-wire HW SPI port. This does not control the nSEL pin. The nSEL
pin is controlled separately by RF_NSEL_PIN.
The SpiWrite() function sends data through the SPI port (8 bits length). The nSEL pin is controlled separately by
RF_NSEL_PIN.
The SpiReadWrite() function sends and reads data via the SPI port (8 bits length). The nSEL pin is controlled
separately by RF_NSEL_PIN.
The SpiRfWriteAddressData() function sends data through the SPI port (16 length - 8 bits address, 8 bits data).
This function controls the nSEL pin.
The SpiRfWriteAddressData() function reads the current value of the register. This function controls the nSEL pin.
