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. In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to VDD

are not implemented). See Section 12 "I/O PORTS" on page 39 and Section 16.8 "I/O PORT PIN CHAR-

ACTERISTICS" on page 128 for more details.

3. OSC1 and OSC2 pins connect a crystal or ceramic resonator, an external RC, or an external source to

the on-chip oscillator see Section 3 "PIN DESCRIPTION" on page 7 and Section 16.5 "CLOCK AND TIM-

ING CHARACTERISTICS" on page 116 for more details.
