8.3.3.2 Selectable UART transfer speeds
Remark: Signals DTRQ and MX can be disabled by clearing TestPinEnReg register’s
RS232LineEn bit.
The internal UART interface is compatible with an RS232 serial interface.
The default transfer speed is 9.6 kBd. To change the transfer speed, the host controller
must write a value for the new transfer speed to the SerialSpeedReg register. Bits
BR_T0[2:0] and BR_T1[4:0] define the factors for setting the transfer speed in the
SerialSpeedReg register.
The BR_T0[2:0] and BR_T1[4:0] settings are described in
transfer speeds and the relevant register settings are given in
Table 9.
Table 10.
