As of version 1.0.0.8.post1 the pyermassi module can be configured to
raise exceptions instead of returning an error code. To use this feature
you have to set the variable RAISE_EXCEPTIONS to True. Example:
>>> import pyermassi as ssi
>>> ssi.RAISE_EXCEPTIONS = True
If a function requests an encoder number as parameter this can be one of
EncoderNr1
...
EncoderNr16
Encoder types can be either NO_ENCODER or GENERIC_SSI.
Clock values in SSIGetSSIClock and SSISetSSIClock can be one of

SSICLK100K // 100 kHz
SSICLK200K // 200 kHz
SSICLK500K // 500 kHz
SSICLK1M // 1,0 MHz
