Notes:

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. Input mode can be used for general purpose I/O, output mode cannot be used.

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

1 and Section 12.5 "CLOCK AND TIMING CHARACTERISTICS" for more details.

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