Explanation
Index0 Index low byte (Unsigned16, LSB)
Index1 Index high byte (Unsigned16, MSB)
SubIdx Sub-index (Unsigned8)
Data0 Data low low byte (LLSB)
Data3 Data high high byte (MMSB)
Parameters whose data type is Unsigned8 are transmitted in byte D0, parameters whose type is Unsigned16
use D0 and D1.
The number of valid data bytes is coded as follows in the first CAN data byte (0x4x):
