The transmit speed port is used to select the transmit speed for each of the ports
installed. 1 = 100 KHz. and 0 = 12-14.5Khz. operation. The spare bits are read-write.
Please note that the 3282 programming needs to match the CNTL2 selections for
speed.
This is a legacy register retained for software commonality but has no effect on
operation. The new transmitter does not require this input.
