Preliminary
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.
Positive supply connection
Return supply connection
DD
- 1.0V when outputting a logical ‘1’.
