Hi, I am designing the SPI master to load the registers for config the ADF5902, please help me to answer this questions:
1.- according to the datasheet (fig2) and the timing diagram of the SPI protocol I understand that the correct values for the ADF5902 are CPOL = 0 and CPHA = 0, is this correct?
2.- according to the datasheet (fig2) I must send 32 bits at each transaction (1 register) at time right?, then pull high LE, wait, pull down the LE, send the register number 2 and repeat the process until config all the registers needed?
SPI image changed to a better one
