Function
Reset Input Pin, Active Low. This pin has an internal, weak pull-up resistor to
REG_DVDD. If this pin is not being used it can be left not connected. For
added security and robustness, it is recommended that this pin be strapped
via a resistor to REG_DVDD.
General Purpose Digital I/O 5 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 5
External Interrupt Request 1, Active High
Receive Data for UART Serial Port
This Pin may also be used as a clock input to Timer1.
General Purpose Digital I/O 6 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 6
Transmit Data for UART Serial Port
General Purpose Digital I/O 7 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 7
External Interrupt Request 4, Active High
General Purpose Digital I/O 8 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 8
External Interrupt Request 5, Active High
This Pin may also be used as a clock input to Timer1.
JTAG Test Clock. This clock input pin is one of the standard 5 pin JTAG debug
port on the part. TCK is an input pin only and has an internal weak pull-up
resistor. If not being used this pin can be left unconnected
JTAG Test Data Input. This data input pin is one of the standard 5 pin JTAG
debug port on the part. TDI is an input pin only and has an internal weak pull-
up resistor. If not being used this pin can be left unconnected
Ground Reference for On-Chip Digital Circuits
No Connect, this pin is not connected internally but is reserved for possible
future use, this pin should therefore not be connected externally
JTAG Test Data Output. This data output pin is one of the standard 5 pin JTAG
debug port 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. If not being
used this pin can be left unconnected
JTAG Test Reset. This Reset input pin is one of the standard 5 pin JTAG debug
port on the part. NTRST is an input pin only and has an internal weak pull-
down resistor. If not being used this pin can be left unconnected. 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 port on the part. TMS is an input pin only and has an internal
weak pull-up resistor. If not being used this pin can be left unconnected
