NOTES:
1. V_CC must be applied before or at the same time as G\ /V_PP and removed after or at the same time as G\ /V_PP. The deivce must not be inserted into or
removed from the board when G\ /V_PP or V_CC is applied.
2. G\ /V_PP can be connected to V_CC directly (except in the program mode). V_CC supply current in this case is I_CC + I_PP.
