Notes:
1. In the interrupt input column, “ei
column (wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input,
else the configuration is floating interrupt input.
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
ACTERISTICS" on page 128
3. OSC1 and OSC2 pins connect a crystal or ceramic resonator, an external RC, or an external source to
the on-chip oscillator see
