49 P4 Output
Input/
Output
In reset,
output is
disabled,
pull-up is
enabled
Transmit Data — SCI1 transmit data output
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
After reset, the default state is SCI output.
To deactivate the internal pull-up resistor, clear bit 6 in the
GPIOD_PUR register.

Input/
Output
Input,
pull-up
enabled
Receive Data — SCI1 receive data input
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
After reset, the default state is SCI input.
To deactivate the internal pull-up resistor, clear bit 7 in the
GPIOD_PUR register.
TCK 137 D8 Schmitt
Input
Input,
pulled low
internally
Test Clock Input — This input pin provides a gated clock to
synchronize the test logic and shift serial data to the
JTAG/EOnCE port. The pin is connected internally to a pull-down
resistor.
TMS 138 A8 Schmitt
Input
Input,
pulled high
internally
Test Mode Select Input — This input pin is used to sequence the
JTAG TAP controller’s state machine. It is sampled on the rising
edge of TCK and has an on-chip pull-up resistor.
To deactivate the internal pull-up resistor, set the JTAG bit in the
SIM_PUDR register.
Note: Always tie the TMS pin to V
DD
through a 2.2K resistor.
TDI 139 B8 Schmitt
Input
Input,
pulled high
internally
Test Data Input — This input pin provides a serial input data
stream to the JTAG/EOnCE port. It is sampled on the rising edge
of TCK and has an on-chip pull-up resistor.
To deactivate the internal pull-up resistor, set the JTAG bit in the
SIM_PUDR register.
TDO 140 D7 Output In reset,
output is
disabled,
pull-up is
enabled
Test Data Output — This tri-stateable output pin provides a serial
output data stream from the JTAG/EOnCE port. It is driven in the
shift-IR and shift-DR controller states, and changes on the falling
edge of TCK.
