3.2.10.2 Read Mode

As NCS and NRD waveforms are defined independently of one another, the SMC needs to know when the read data is available on the data bus. The SMC does not compare NCS and NRD timings to know which signal rises first. The READ_MODE parameter in the HSMC_MODE register of the corresponding chip select indicates which signal of NRD and NCS controls the read operation.
