SERIAL INPUT TIMING
Notes: 1.
These parameters are periodically sampled and not 100% tested.
2.
tWC is the time from the rising edge of CS after a valid nonvolatile write sequence, to the end of the self-timed internal non-volatile write
cycle. It is the minimum cycle time to be allowed for any non-volatile write cycle by the user, unless the “WIP” bit is used to check for the
end of the write cycle.
