RD2—Noise Margin Register
RD2 provides a calculated, logarithmic noise margin value which is used by the EMDP state
machine. This coded noise margin value is according to ETSI ETR 152 recommendation. The
noise margin value is always available, but it is recalculated and updated only every 64 baud.
17
The indicated noise margin is affected by the setting of the Gain Control Register (WR9). If the
receiver gain is increased by 6 dB, the indicated noise margin must be decreased by 6 dB.
B7:B0
