Use NWE_SETUP, NWE_PULSE and NWE_CYCLE to define the write enable waveform
according to datasheet of the device.
Use TADL field in the SMC_TIMINGS register to configure the timing between the last address
latch cycle and the first rising edge of WEN for data input.
Figure 27-32. Write Enable Timing Configuration
Use NRD_SETUP, NRD_PULSE and NRD_CYCLE to define the read enable waveform accord-
ing to the datasheet of the device.
Use TAR field in the SMC_TIMINGS register to configure the timings between address latch
enable falling edge to read enable falling edge.
Use TCLR field in the SMC_TIMINGS register to configure the timings between the command
latch enable falling edge to the read enable falling edge.
