Data Sheet
TCLKO
RTS
Transmit Clock Output
This bit is only valid in high speed operation mode, i.e. clock mode 4 and
CCR0.HS = ’1’.
In high speed mode the internal transmit clock is supplied to pin RTS as
an output.
TCLKO=’0’
TCLKO=’1’
Request To Send pin control
The request to send pin RTS can be controlled by the DSCC4 as an
output autonomously or via setting/clearing bit ’RTS’.
This bit is not valid in high speed operation mode.
RTS=’0’
RTS=’1’
Note: For RTS pin control a transmit clock is necessary.
Pin RTS is an unused input signal in high speed operation
mode.
It should be connected to a known level via a pull-up/down
resistor.
The internal transmit clock is supplied as an output signal
to pin RTS.
RTS (output) pin is controlled by the DSCC4
autonomously.
• In HDLC modes RTS is activated during transmission.
• In ASYNC and BISYNC mode, the function depends on
