Notes:
1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up
column (wpu) is merged with the interrupt column (int), then the I/O configuration is a pull-up interrupt in-
put, otherwise the configuration is a floating interrupt input. Port C is mapped to ei0 or ei1 by option byte.
2. In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to V
are not implemented). See
3. OSC1 and OSC2 pins connect a crystal or ceramic resonator, an external RC, or an external source to
the on-chip oscillator see
