The user setting
specifies whether the UART uses flow control or not.
Bit no.
Description
0
Set this Bit to 1 to enable the flow control pins
and
1-7
Reserved.
For baud rates faster than 230400 Baud, the flow control pins
and
are enabled.
The evaluation board Proteus-II-EV version 2.0 does not provide the connection
between the flow control pins of the module and the evaluation board’s USB
port. Thus in this version of the Proteus-II-EV the flow control can be only
used, if the on-board UART is disconnected (remove respective jumpers on
JP2) and all UART lines (
and
) are connected to an
external FTDI cable.
