Hello group I am attemping to count 2Mhz PWM clock cycles @ 50% duty sent to slave device from DP256B EVB and am not having much luck. My slave device is hard coded to transmit I/O at CLK/32 and I would like to be able to clock slave device while counting clock cycles and still be able to recieve slave devi
