These 16-bit registers set the threshold values. When in attack phase and the Attack Threshold is exceeded the
Compressor attenuation is incremented by stepsize (see LMTCTRL). When in release phase and the Release Threshold is
not exceeded the Compressor attenuation is incremented by stepsize (but not above 0).

step time units = 1<<step_time, units in GAINCTRL_LO bit 5
8’hFF would equal threshold level of +2.0dB. Each step below
this 8-bit full scale value reduces threshold level by 0.0078 dB.
Always 0. It isn’t necessary to provide threshold resolution to
the point where these lower 8 bits would be used.
Always 0. It isn’t necessary to provide threshold resolution to

1 = value in bits 6:0 is in 10ms units, otherwise 1ms units.
Timer value in units of 1 or 10ms.
8’hFF would equal threshold level of +2.0dB. Each step below
this 8-bit full scale value reduces threshold level by 0.0078 dB.
