Resolver Single-turn SSI - 12 upper bits set to 0, 12 lower bits for
position within one turn. Configurable for Gray or binary
code.
Sin-Cos (single-turn)
Sin-Cos Single-turn SSI - 12 upper bits set to 0, 12 lower bits for
position within one turn (SSIMODE 0). Configurable for
Gray or binary code.
Multi-turn SSI - 12 upper bits for turns count, 12 lower bits
for position within one turn (SSIMODE 1). Configurable for
Gray or binary code.
