Receiver clock.
In
the synchronous
mode, the
RXC
has the same rate
(frequency)
as
the baud rate used.
In
the asynchronous mode, the RXe
has a rate which
is
a multiple
of
the
baud rate used: i.e.
1, 16, or 64 times
the baud rate depending on the mode
instruction.
Transmitter
clock; functionaly the
same
as
RXC,
for transmission.
