I/O

Data Input/Output – Schmitt Trigger Input

Program/Verify mode

Legend: I = Input, O = Output, P = Power

Note 1:

The programming high voltage is internally generated. To activate the Program/Verify mode, high voltage

needs to be applied to MCLR input. Since the MCLR is used for a level source, MCLR does not draw any

significant current.
