For resolvers = pole pair number setting.
Assignment of the indices: Index [n-1] --> Encoder n

Generating the two's complement.
Gn_XIST1 is a free-running position value.
The external control must process the overflows.
The contents of r0483/r2723 are determined by the encoder
status word/control word. Refer to [4720] and [4730].
