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 Input/Output 5, External Interrupt Request 1, or Receive Data. This is a
multifunction pin. By default and after power-on-reset, this pin configures as an input. The pin
has an internal weak pull-up resistor and when not in use, it can be left unconnected. This
multifunction pin can be configured in one of three states, namely:
General Purpose Digital Input/Output 6, Transmit Data. This is a multifunction pin. By default
and after power-on-reset, this pin configures as an input. The pin has an internal weak pull-up
resistor and when not in use, it can be left unconnected. This multifunction pin can be
configured in one of two states, namely:
General Purpose Digital Input/Output 7, External Interrupt Request. This is a multifunction pin.
By default and after power-on-reset, this pin configures as an input. The pin has an internal
weak pull-up resistor and when not in use, it can be left unconnected. This multifunction pin
can be configured in one of two states, namely:
General Purpose Digital Input/Output 8, External Interrupt Request. This is a multifunction pin.
By default and after power-on-reset, this pin configures as an input. The pin has an internal
weak pull-up resistor and when not in use, it can be left unconnected. This multifunction pin
can be configured in one of two states, namely:
JTAG Test Clock. This clock input pin is one of the standard 5-pin JTAG debug ports on the part.
TCK is an input pin only and has an internal weak pull-up resistor. This pin can be left
unconnected when not in use.
