I/O = input/output
P = power
— = Not used
TTL = TTL input
ST = Schmitt Trigger input
Note 1:
This buffer is a Schmitt Trigger input when congured as an external interrupt.
2:
This buffer is a Schmitt Trigger input when used in serial programming mode.
3:
This buffer is a Schmitt Trigger input when congured as general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
4:
This buffer is a Schmitt Trigger input when congured in RC oscillator mode and a CMOS input otherwise.
