Function
JTAG Test Data Input. This data input pin is one of the standard 5-pin JTAG debug ports on the
part. TDI is an input pin only and has an internal weak pull-up resistor. This pin can be left
unconnected when not in use.
Ground Reference for On-Chip Digital Circuits.
No Connect. These pins are not internally connected, but are reserved for possible future use.
Therefore, do not externally connect these pins. These pins can be grounded, if required.
JTAG Test Data Output. This data output pin is one of the standard 5-pin JTAG debug ports on
the part. TDO is an output pin only. On power-on, this output is disabled and pulled high via an
internal weak pull-up resistor. This pin can be left unconnected when not in use.
JTAG Test Reset. This reset input pin is one of the standard 5-pin JTAG debug ports on the part.
NTRST is an input pin only and has an internal weak pull-down resistor. This pin can be left
unconnected when not in use. NTRST is also monitored by the on-chip kernel to enable LIN
boot-load mode.
JTAG Test Mode Select. This mode select input pin is one of the standard 5-pin JTAG debug
ports on the part. TMS is an input pin only and has an internal weak pull-up resistor. This pin
can be left unconnected when not in use.
Battery Voltage Input to Resistor Divider.
External Reference Input Terminal. When this input is not used, connect it directly to the AGND
system ground.
Switch to Internal Analog Ground Reference. This pin is the negative input for the external
temperature channel and external reference. When this input is not used, connect it directly to
the AGND system ground.
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.
Nominal 2.6 V Output from On-Chip Regulator.
General Purpose Digital Input/Output 0, External Interrupt Request 0, or SPI Interface. This 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
multifunction pin can be configured in one of three states, namely:
General Purpose Digital Input/Output 1, SPI Interface. This 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 Input/Output 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 Input/Output 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 0
External Interrupt Request 0, active high
SPI interface, slave select input
General purpose digital I/O 1
SPI interface, serial clock input
General Purpose Digital I/O 2
SPI Interface, Master Input/Slave Output Pin
General Purpose Digital I/O 3
SPI Interface, Master Output/Slave Input Pin
