This register allows the user to program control the adaptation speed of the Acoustic Echo Canceller. This register value
changes dynamically when the ’ASC-’ bit in the Acoustic Echo Canceller Control Register is low. The ’ASC-’ bit must be 1
when this register is under user control. The valid range is from 0000h to 7FFFh. The high byte is in Register 2 and the low
byte is in Register 1. Smaller values correspond to slower adaptation speed.
