Bit 0 = 1: SPECIAL MX648: Turns off external charging
with FO1.
Bit 1 = 1: DIESEL-MECHANICAL: No RPM
increase when braking (see CV #364).
Bit 2 = 0: old RailCom format with ID 4.
= 1: current RailCom (kph) feedback with ID 7.
Bit 3 = 1: “Looped” driving sounds will be faded
out when switching to a different sound.
Bit 4 = 1: Slows steam chuff frequency at high speed
Bit 5 = 1: Braking (even by one speed
step) causes the motor and turbo
sounds to decrease by on sound step.
Bit 6 = 1: Thyristor volume increases when braking
Bit 7 = 1: SPECIAL MX645: ELECTRIC: Flashes
of light (approx. 0.1 sec) on FO7 when
switch gear sound is played.
