Specifications
Table 28. NFC Target Timing Parameters1,2
1. High is defined as 80% of signal value and low is defined as 20% of signal value. All timings are listed according to this NFC
clock frequency (multiples of NFC clock period) except NF16, which is not NFC clock related.
2. The read data is generated by the NAND Flash device and sampled with the internal NFC clock.
