Function
Battery Voltage Input to resistor divider
External Reference Input Terminal. If this input is not being used it should be
connected directly to the AGND system ground
Switch to internal analog ground reference.
Negative input for external temperature channel and external reference
If this input is not being used it should be connected directly to the AGND
system ground.
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
External Pin for NTC/PTC temperature measurement
Positive Differential Input for Current Channel
Negative Differential Input for Current Channel
Ground Reference for On-Chip Precision Analog Circuits
Ground Reference for On-Chip Precision Analog Circuits
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
Nominal 2.6V output from on chip regulator
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
General Purpose Digital I/O 0 is a Multi-Function Pin. By default and after
Power-On-Reset, this pin is configured as an input. The pin has an internal
weak pull-up resistor and if not being used it can be left unconnected. This
multi-function pin can be configured in one of 3 states, namely:
General Purpose Digital I/O 0
External Interrupt Request 0, Active High
SPI Interface, Slave Select Input
General Purpose Digital I/O 1 is a Multi-Function Pin. By default and after
Power-On-Reset, this pin is configured as an input. The pin has an internal
weak pull-up resistor and if not being used it can be left unconnected. This
multi-function pin can be configured in one of 2 states, namely:
General Purpose Digital I/O 1
SPI Interface, Serial Clock Input
General Purpose Digital I/O 2 is a Multi-Function Pin. By default and after
Power-On-Reset, this pin is configured as an input. The pin has an internal
weak pull-up resistor and if not being used it can be left unconnected. This
multi-function pin can be configured in one of 2 states, namely:
General Purpose Digital I/O 2
SPI Interface, Master Input/Slave Output Pin
General Purpose Digital I/O 3 is a Multi-Function Pin. By default and after
Power-On-Reset, this pin is configured as an input. The pin has an internal
weak pull-up resistor and if not being used it can be left unconnected. This
multi-function pin can be configured in one of 2 states, namely:
General Purpose Digital I/O 3
SPI Interface, Master Output/Slave Input Pin
General Purpose Digital I/O 4 is a programmable digital I/O pin. By default and
after Power-On-Reset, this pin is configured as an input. The pin has an
internal weak pull-up resistor and if not being used this pin can be left
unconnected.
GPIO4 is can also be configured to output a 2.56MHz clock
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
