pins respectively. When the SB3 pins of Channel 1 to Channel 4 are configured as outputs, the control data is written to these four SB3
pins via the SB3[0] to SB3[3] bits respectively.

GREG18: Level Meter Result Low Byte, Read Only (31H)
This register contains the low byte of the level meter result. The default value is 00H.
The LVLL[0] bit in this register will be set to ‘1’ when the level meter result (both high and low bytes) is ready, and it will be reset to ‘0’
immediately after the high byte of result is read. To read the level meter result, it is recommended to the low byte first, then read the high
byte (LVLH[7:0] in GREG19).
GREG19: Level Meter Result High Byte, Read Only (32H)
This register contains the high byte of the level meter result. The default value is 00H.
GREG20: Level Meter Count Number, Read/Write (33H/B3H)
The CN[7:0] bits are used to set the number of time cycles for sampling the PCM data.
CN[7:0] = 0 (d):
the PCM data is output to the result registers GREG18 and GREG19 directly;
CN[7:0] = N (d):
the PCM data is sampled for N

μ
s (N is from 1 to 255).
GREG21: Level Meter Channel and Linear/Compressed Mode Selection, Level Meter On/Off, Read/Write (34H/B4H)
The Level Meter On/Off bit (LMO) enables/disables the level meter.
LMO = 0:
The level meter is disabled (default);
LMO = 1:
The level meter is enabled.
The Linear/Compressed bit (L/C) determines the mode of level meter operation.
L/C = 0:
Message mode is selected. The compressed PCM data will be output to GREG19 transparently (default).
L/C = 1:
Metering mode is selected. The linear PCM data will be metered and the result will be output to the registers
GREG18 and GREG19.
