In STS configuration = "00", STS is V
executing internal erase or program algorithms.
STS configuration codes "01", "10" and "11" are all pulse
modes such that the STS pin pulses low then high when the
operation indicated by the configuration code is completed.

00 = level mode: RY/BY# indication. (Default)
01 = pulse mode on erase complete.
10 = pulse mode on program complete.
11 = pulse mode on erase or program complete.
