1. All 5 V tolerant digital I/O pins are internally clamped to V
SS
through an ESD protection diode. There is no diode
connection to V
DD
. If V
IN
is less than V
DIO_MIN
, a current limiting resistor is required. The negative DC injection current
limiting resistor is calculated as R=(V

2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. Additionally, EXTAL and
XTAL are analog pins.
3. All analog pins are internally clamped to V
SS
and V
DD
through ESD protection diodes. If V
IN
is less than V
AIO_MIN
or greater
than V
AIO_MAX
, a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as
R=(V

larger of these two calculated resistances if the pin is exposed to positive and negative injection currents.
4. Open drain outputs must be pulled to VDD.
