- QSPI CLK
- QSPI CS
I am trying to validate the QSPI Setup time and Hold time parameters for the Data IO Lines with respect to the clock.
The data and clock lines are connected directly to the Micro with only a 47ohm 0603 resistor in series.
But if you check the Table 65 of the MCU datasheet (page 119), it is given as Setup time for incoming data and hold time for incoming data.
I am using 500MHz scope.
My doubts :
If I probe the data lines, how will I know whether the data transitions in the IO Lines are incoming data or outgoing data?
Apart from Setup time and Hold time validation, what are the other parameters I have to measure for validating QSPI lines from hardware perspective?
