GREG18: Level Meter Result Low Byte, Read Only (31H)
GREG19: Level Meter Result High Byte, Read Only (32H)
GREG20: Level Meter Count Number, Read/Write (33H/B3H)
GREG21: Level Meter Channel and Linear/Compressed Mode Selection, Level Meter On/Off, Read/Write (34H/B4H)
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.
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).
This register contains the high byte of the level meter result. The default value is 00H.
The CN[7:0] bits are used to set the number of time cycles for sampling the PCM data.
CN[7:0] = 0 (d):
CN[7:0] = N (d):
The Level Meter On/Off bit (LMO) enables/disables the level meter.
LMO = 0:
LMO = 1:
The Linear/Compressed bit (L/C) determines the mode of level meter operation.
L/C = 0:
L/C = 1:
GREG18 and GREG19.

the PCM data is output to the result registers GREG18 and GREG19 directly;
the PCM data is sampled for N × 125
The level meter is disabled (default);
The level meter is enabled.
Message mode is selected. The compressed PCM data will be output to GREG19 transparently (default).
Metering mode is selected. The linear PCM data will be metered and the result will be output to the registers
