since arbitrarily narrow pulses can be generated at the out-
put of the multiplexer when it changes state.
The BRG is enabled while bit DO of WR14 is set to 1 and
disabled while this bit is set to 0 and it is disabled after a
hardware reset. To prevent metastable problems when the
baud rate generator is first enabled, the enable bit is
synchronized to the baud rate generator clock. This

introduces an additional delay when the baud rate
generator is first enabled. This is shown in Figure 3-2. The
baud rate generator is disabled immediately when bit D0
of WR14 is set to “0,” because the delay is only necessary
on start-up. The baud rate generator may be enabled and
disabled on the fly, but this delay on start-up must be taken
into consideration.
