A2 coefficient of the second biquad of the IIR filter.
Used to set process tune ramp down limit of clock cycles.
PTUNEUPLIMIT along with PTUNEHYS set up the RC time con-
stant range for the filters.
Used to set process tune ramp down hysteresis range of clock
cycles. PTUNEHYS along with PTUNEUPLIMIT set up the RC time
constant range for the filters.
Reserved
Sets AGC gain freeze time offset. Internal timer is 12 bits and
lower 6-bit word is 0x1C (1500 ADC clock-cycle delay). EN30U
(bit 11) should be set to use this mode.
A1 coefficient of the second biquad of the IIR filter.
