Description
General purpose I/O or programmable reference B
output.
Analog input channel 4. This pin can also serve as a
GPIO.
Analog input channel 5. This pin can connect to a level
shift network. If enabled, a +0.5V offset is added to the
input voltage. This pin can also serve as a GPIO.
Analog input channel 6. This pin can also serve as a
GPIO.
Analog input channel 7. This pin can also serve as a
GPIO.
This pin is an output to control the gate of an external
N-FET for voltage regulation.
IN Mode: Input with weak pull-up resistor, can be used to
generate an interrupt.
HS Mode: External oscillator input.
IN Mode: General purpose output.
HS Mode: External oscillator/clock output.
Master clear (reset) input / programming voltage input.
This pin is an active low reset to the device.

Definition:
TTL-compatible input
CMOS-compatible input or output
Schmitt Trigger input, with CMOS levels
SMBus compatible input
Open-drain output. An external pull-up resistor is required if this pin is used as an output.
N-channel pull-up. This pin will pull-up to approximately VDD - 1.0V when outputting a logical ‘1’.
Weak internal pull-up (10K-50K ohms)
No P-diode to VDD. This pin may be pulled above the supply rail (to 6.0V maximum).
