S_V_LIMIT_B
SLS speed limit with a 32-bit resolution with sign bit.
● The SLS speed limit is available in r9733[2].
● Bit 31 determines the sign of the value:
– Bit = 0 → positive value
– Bit = 1 → negative value
● The SLS speed limit is standardized via p2000.
S_V_LIMIT_B = 4000 0000 hex ≐ speed in p2000
