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 8 ”I/O PORTS” on page 38 and Section 12.8 ”I/O PORT PIN CHAR-
ACTERISTICS” on page 145 for more details.
3. OSC1 and OSC2 pins connect a crystal/ceramic resonator or an external source to the on-chip oscillator
see Section 1.2 ”PIN DESCRIPTION” on page 7 and Section 12.5 ”CLOCK AND TIMING CHARACTER-
ISTICS” on page 138 for more details.
