Freescale Semiconductor, Inc.
M68HC16 to change clock frequencies on the fly.
In this particular case, we alternate between
a frequency of 16.78MHz and 4.194MHz.
that because we are writing to the screen,
we also need to correct the BAUD rate (1200)
each time we change the frequency.
that your terminal has been set up to receive
at 1200 baud.
to the CLKOUT pin on the EVB to observe the
frequency change.
