7.2.3 Signed Integer
For signed integers, the most significant bit (msb) represents the sign of the value, where
0=positive and 1=negative. Signed integers are represents in 2’s compliment.
Signed 32-Bit Integer (SInt32)
SInt32-based parameters are signed 32-bit numbers (2’s compliment). Bit 31
represents the sign of the value, where 0=positive and 1=negative.
