CV 29
Configuration Register 1
Description
CV 29 contains miscellaneous decoder configuration bits:
Bit 0: DIR, Direction Bit
0 = normal operation
1 = direction bit in Speed/Direction instruction is inverted
before processing.
Bit 1: F0 Location
0 = F0 state is controlled by bit 4 of Speed/Direction
Instruction (14 Speed Step Mode)
1 = F0 state is controlled by bit 4 of Function Group 1
Instruction (28 and 128 Speed Step Modes)
Bit 2: APS, Alternate Power Source enable
0 = NMRA Digital Only
1 = Alternate Power Source enabled as set by CV 12
Bit 3: ACK, Advanced Acknowledge Mode enable (not used)
0 = Advanced Acknowledge mode disabled.
1 = Advanced Acknowledge mode enabled.
Bit 4: STE, Speed Table Enable
0 = Standard Speed Table
1 = Use custom speed table selected by CV 25.
Bit 5: EAM, Extended Address Mode enable
0 = Decoder responds to Primary Address in CV 1
1 = Decoder responds to Extended Address in CV 17-18
Bit 6: Reserved for future use.
Bit 7: Multifunction Decoder - Always reads as 0.
When the DIR bit is set, the locomotive and headlight will run in a direction
opposite to the speed/direction instruction received. This bit is mostly useful
for diesel locomotives that are run long hood forward and has little use for
steam operation.
The F0 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
