NOTES
16. E (bar), G (bar), NE (bar) and W (bar) must make the transition between VIH(max) to VIL(max), or VIL(max) to VIH(min) in a
monotonic fashion.
17. Measured with W (bar) and NE (bar) both returned high, and G (bar) returned low. Note that store cycles are inhibited/aborted
by Vcc <3.3V (STORE inhibit).
18. Once twc has been satisfied by NE (bar), G (bar), W (bar) and E (bar) the store cycle is completed automatically, ignoring all
inputs. Any of NE (bar), G (bar), W (bar) or E (bar) may be used to terminate the store initiation cycle.
