Sending data from MCU to transceiver : problem with understanding the datasheet.

Hi,


I will have to program a transceiver, it’s a SPIRIT1 from STMicroelectronics. I have to program it through an SPI interface with a MCU.

One problem is that I don’t know how to send the data from the MCU to the SPIRIT1.

I want to send data to the SYNT0 register, with « 6 band select factor for high band » so field BS = 1, and I want the SYNTH[4:0] field to be 00000, so the byte of the SYNTH0 register is 0000 0001.

If I’m using an ATmega32, PB5 is the MOSI pin. So I assume the code...
