Package pinout and pin description
Table 3.
1. On the chip, each I/O port may have up to 8 pads. Pads that are not bonded to external pins are in input pull-up
2. It is mandatory to connect all available V
3. OSC1 and OSC2 pins connect a crystal/ceramic resonator or an external source to the on-chip oscillator; see
