signal and remains valid until the rising edge of NCS. Data must be sampled when NCS is raised. In that case, the
READ_MODE must be set to 0 (read is controlled by NCS): the SMC internally samples the data on the rising edge of
Master Clock that generates the rising edge of NCS, whatever the programmed waveform of NRD may be.
