MC56F825x/MC56F824x Signal Pins
After reset, each pin is configured for its primary function (listed first). Any alternative functionality, shown in parentheses and
as italic, must be programmed via the GPIO module’s peripheral enable registers (GPIO_x_PER) and the SIM module’s GPIO
peripheral select (GPSx) registers.

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 pullup resistor.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDI.

shift-IR and shift-DR controller states, and changes on the falling
edge of TCK.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDO.

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 pullup resistor. A
Schmitt-trigger input is used for noise immunity.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TCK
