Note
 Some SSI devices require 24V power which has to be brought in
externally. Pins #4, and #12 are unused in this case, leave floating.
 Hardware capture is not available with Serial Data encoders
Configuring SSI
Configuring the SSI protocol requires the programming of two essential control registers:
 Global Control Registers
 Channel Control Registers
The resulting data is found in:
 SSI Data Registers
