are not implemented). See See “I/O PORTS” on page 40. and Section 12.8 I/O PORT PIN CHARACTER-

ISTICS for more details.

3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscil-

lator; see Section 2 PIN DESCRIPTION and Section 12.5 CLOCK AND TIMING CHARACTERISTICS for

more details.

4. On the chip, each I/O port has 8 pads. Pads that are not bonded to external pins are in input pull-up con-

figuration after reset. The configuration of these pads must be kept at reset state to avoid added current

consumption.

5. It is mandatory to connect all available VDD and VREF pins to the supply voltage and all VSS and

VSSA pins to ground.
