The LM_CN[7:0] bits in this register together with the LM_CN[10:8] bits in GREG16 form an 11-bit counter register, which is used for the
level meter to set the time period for PCM data sampling.
The maximum number of time cycles set by the LM_CN[10:0] bits is 7FFH, corresponding to 255.875 ms. The time period for sampling
can be programmed from 0 ms to 255.875 ms in steps of 0.125 ms (8k). If the LM_CN[10:0] bits are set to be 000H (corresponding to 0
ms), the PCM data will be transmitted transparently to the level meter result registers without being sampled.

LM_CN[10:0] = 0 (d): The PCM data is transmitted to level meter result registers GREG17 and GREG18 directly (default);
LM_CN[10:0] = N (d):The PCM data is sampled for N ∗ 125 µs (N from 1 to 2047).
RHS_C
Receive PCM highway selection for part C in three-party conference
RHS_C = 0:
RHS_C = 1:
Receive time slot selection for part C in three-party conference.
The valid value of the RT_C[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of RT_C[6:0] is 0(d).

THS_D = 0:
THS_D = 1:
Transmit time slot selection for part D in three-party conference.
The valid value of the TT_D[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of TT_D[6:0] is 0(d).
