Freescale Semiconductor

Preliminary

RXD1

(GPIOD7)

Input

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

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

116

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 VDD through a 2.2K resistor.

TDI

117

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

118

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.
