Functional Description of Register Bits
This register allows the user to program the level of the Non-Linear Processor Threshold (NLPTHR). The 16
bit 2’s complement linear value defaults to 0CE0

Functional Description of Register Bits
This register allows the user to program the level of MU, which is the LMS filter step size. Increasing this
value can speed up convergence times, but can also potentially decrease VEC stability. MU is a 16 bit 2’s
complement value which defaults to 4000
hex
= 1.0 The maximum value is 7FFF
hex
or 1.9999 decimal. The
high byte is in Register 2 and the low byte is in Register 1.
