Parameter
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.
The read data is generated by the NAND Flash device and sampled with the
internal NFC clock.
