6.5.2.3 Protocol functions
The following functions encapsulate the above-described bus functions. The parameter sequences are identical. The CRC16
checksum is not included here, as it is calculated and checked in the DLL. Some parameters consist of several bytes. These are
grouped together for the sake of clarity. The different requests a and b pertaining to function 95 are split into two functions: F95
and F95val.
Functions F34, F35, F64, F65 and F101 are only listed here for the sake of completeness, and are of no relevance in these
devices. Function F32 and F33 are new functions which are aviable in the s30c.dll from the 12.9.2005 and later.
