Hello Ryan, As per your suggestion we have added positive edge trigger D-flipflop at the output of SDO_A pin and SPI clock is configured for 1MHz, CPOL = 0 and CPHASE = 1. But with these settings we are not able to get proper response for CFR read operation. Following is sequence for CFR read operation from our SPI driver Sequence of operation : Write CFR register (0x804000000000) Read CFR register (0x300000000000) Dummy sequence (0x000000000000) Note : Slave select pin made high and then low before starting every sequence mentioned after dummy sequence command in response we get data as shown below (in hex): 0 0 20 a0 0 0 Please help us to understand if there is any missing configuration from our side Regards, Sachin Dighe
