56F8014 Technical Data, Rev. 9
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.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDO.
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
SPI Serial Clock — In the master mode, this pin serves as an
output, clocking slaved listeners. In slave mode, this pin serves as
the data clock input. A Schmitt trigger input is used for noise
immunity.
Serial Data — This pin serves as the I
After reset, the default state is GPIOB0. The peripheral functionality
is controlled via the SIM. See
Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
SPI Slave Select — SS is used in slave mode to indicate to the SPI
module that the current transfer is to be received.
Serial Clock — This pin serves as the I
After reset, the default state is GPIOB1. The peripheral functionality
is controlled via the SIM. See
