3.5.25 Register 33h (67h), Demodulator Loop Stress Status
This register, in conjunction with the demodulator offset nulling register 3Eh,
forms a demodulator tracking loop. The following figure illustrates the breakout
of register bit assignments.

Table 3.5.33: Demodulator Loop Stress Status Register Definition
Loop stress data is read from register 33h in response to offset null loop tuning
values written to register 3Eh. The register contents will become stable accord-
ing the following delay formula:
Settling Delay = 1/(2
