reserved for production tests
internal signal processing in the receiver chain is performed
non-linearly which increases the operating distance in
communication modes at 106 kBd
Remark:
due to non-linearity, the effect of the RxThresholdReg
register’s MinLevel[3:0] and the CollLevel[2:0] values is also
non-linear
reserved for production tests
enables the digital self test
the self test can also be started by the CalcCRC command; see
Section 10.3.1.4 on page 68
the self test is enabled by value 1001b
Remark:
for default operation the self test must be disabled
by value 0000b
