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