Notes for
1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up
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 See “I/O PORTS” on page 50. and
ISTICS
3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscil-
lator; see
more details.
4. 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 configuration after reset. The configuration of these pads must be kept at reset state to avoid add-
ed current consumption.
