uint8_t regWriteVal = 0x09;
uint8_t dataSize = UINT8_C(1);

}
SpiWriteRegister()
Here the function
the length of the value into it.
An alternative approach to send data to the slave device would be achieved by lowering the chip select line to a low
voltage level and then call
voltage level on the chip select line to high would be required.
* CmdProcessorHandle,
is simply called, by passing a register address, a value written to the register and
MCU_SPI_Send()
to transmit then desired data to the slave device. Afterwards, only raising the
uint32_t param2)
