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.
