Data Sheet
FRTS

Flow Control (using signal RTS)
Bit ’FRTS’ together with bit ’RTS’ determine the function of signal RTS:
FRTS, RTS
0,
1,
0,
1,
Note: For RTS pin control a transmit clock is necessary.
Flow Control (using signal CTS)
This bit controls the function of pin CTS.
This bit is not valid in high speed operation mode.
FCTS = ’0’
FCTS = ’1’
Note: In ASYNC mode the transmitter is additionally controlled by in-
band flow control mechanism (if enabled).

Pin RTS is controlled by the DSCC4 autonomously.
RTS is activated (low) as soon as transmit data is
available within the SCC transmit FIFO.
Pin RTS is controlled by the DSCC4 autonomously
supporting bi-directional data flow control.
RTS is activated (low) if the shadow part of the SCC
receive FIFO is empty and de-activated (high) when the
SCC receive FIFO fill level reaches its receive FIFO
threshold.
Forces pin RTS to active state (low).
Forces pin RTS to inactive state (high).
The transmitter is stopped if CTS input signal is inactive
(high) and enabled if active (low).
Note: In character oriented protocol modes (ASYNC,
The transmitter is enabled disregarding CTS input signal.
BISYNC, asynchronous PPP), the current byte is
completely sent even if CTS becomes inactive
during transmission.
