I want to configure the ADF7242 in unmodulated carrier mode.
I was using IEEE 802.15.4 mode prior to this.
1) Can we communicate over SPI during the unmodulated carrier mode?
yes you can write and read over the SPI while using the Tx carrier test mode. see p71 of the datasheet for details on how to enable this test mode.
note you do have to switch to generic packet mode to enable the test mode
