Sets the parameters for the Envelope Measure and Track function

Sets the parameters for the Envelope Measure and Track function.  
This computes an 2**M-length exponetial average of the N-length block maximum of the magnitude of the 
high byte of the input samples.  The parameters are packed as (M<<12)|N into a 16 bit register so the valid 
parameter ranges are (0<N<1024) and (0<M<16).
