hood forward and have little use for steam operation.
The FL bit should be cleared to 0 if you are using the decoder in 14 speed step mode. If you are
using 28 or 128 speed step modes, this bit should be set to 1.
The STE bit must be set to 1 in order to enable any of the speed curves selected using CV 25.
Otherwise, the DSD will provide a linear (straight-line) throttle response.
The EAM bit must be set to 1 in order to activate extended address capability. Note that once this
bit is set, the decoder will respond to commands sent to the extended address only and com-
mands sent to the primary address will be ignored. This can be a problem if you are using a
command station that does not support extended addressing and the bit gets accidentally set. In
such a case, you must connect the DSD to a programming track to gain access to the CV and
clear the bit.
The DSD does not support advanced acknowledgment or alternate power conversion and the
ACK and APS bits will always read as 0.
Default value: 0X02
