Notes:
1.
Typical value for tWHWH1 is 6μs.
2.
Typical value for tWHWH2 is 0.5 sec.
3.
Guaranteed by design, but not tested.
4.
Typical value is 50 sec. The typical chip program time is considerably less than the maximum chip programming time listed, since most bytes program faster than the maximum program
times listed.
