Could someone please help me with the interfacing of ADF7021-N with MSP430F5438A.
i'm finding a few technical difficultites.
1) The ADF datasheet says that the SDATA and SREAD pins are to be used to write/read to and from the registers. however the interfacing diagram shows that these pins are to be connected to GPIO pins on the microcontroller. i tried using a SPI module to write/read from the registers, since i'm not sure how to do this using GPIO pins. Could you please help me there.
2) Also, the TxRxData and TxRxclk and Clkout are used to transmit/recieve actual data, using an spi module. So i can't use this module to set my register values and get a readback test done right? Just confirming.
