NFC Initialization
Prior to any Command and Data Transfer, the SMC User Interface must be configured to meet
the device timing requirements.
Use NWE_SETUP, NWE_PULSE and NWE_CYCLE to define the write enable waveform
according to the device datasheet.
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.
Use NRD_SETUP, NRD_PULSE and NRD_CYCLE to define the read enable waveform accord-
ing to the device datasheet.
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.
