Description
Reset Input Pin. Active low. This pin has an internal, weak, pull-up resistor to REG_DVDD. When
not in use, this pin remains unconnected. 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. This pin remains unconnected when not in use. 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. This pin remains unconnected when not in use. This multifunction pin can be
configured in one of two states, namely
General-Purpose Digital Input/Output 7, External Interrupt Request 4. 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. This pin remains unconnected when not in use. This multifunction pin
can be configured in one of two states, namely
General-Purpose Digital Input/Output 8, External Interrupt Request 5. 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. This pin remains unconnected when not in use. 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 remains
unconnected when not in use.
