Description:

This command performs a function on its input data and issues a raw input with the MSG byte and modified data.

Currently, this command supports only one function.  When NFUNC is 1, this command expects two 2-byte values in its data.  It subtracts the second value from the first and issues a raw input with the MSG byte and 2-byte subtraction result.  If the first value is less than the second value, the subtraction result is set to zero.
