ST = Schmitt Trigger input
This buffer is a Schmitt Trigger input when configured as an external interrupt.
This buffer is a Schmitt Trigger input when used in Serial Verify mode.
This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.
