56F8014 Technical Data, Rev. 9
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
T1 — Timer, Channel 1
FAULT3 — This fault input pin is used for disabling selected PWM
outputs in cases where fault conditions originate off-chip.
After reset, the default state is GPIOB5. The peripheral functionality
is controlled via the SIM. See
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-up 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.
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.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TMS.
Note:
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.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDI.
Always tie the TMS pin to V
