Data Sheet
FLON
Flow Control Enable
In ASYNC mode, in-band flow control is supported:
FLON=’0’
FLON=’1’
No automatic in-band flow-control is performed. However
recognition of a flow control character (XON/XOFF)
causes always a maskable interrupt event.
Automatic in-band flow-control is performed.
Reception of a XOFF character (defined in register XNXF)
turns off the transmitter after the currently transmitted
character has been shifted out completely (XOFF state).
Reception of a XON character (defined in register XNXF)
resumes the transmitter from XOFF into XON state ready
to send available transmit data bytes.
The current flow control state is indicated via bit ’FCS’ in
register Star.
Any transmitter reset switches the flow-control logic to
XON state.
