In Asynchronous mode (MODE =
‘b000), steering takes effect at the end of
the instruction cycle that writes to STRx. In Asynchronous Steering mode, the output
signal may be an incomplete waveform (see the figure below). This operation may be
useful when the user firmware needs to immediately remove a signal from the output
pin.
