Description of level meter mode
(see Timing Chart 1-4.)
When the LSI is set to this mode, it performs digital level meter functions.
When the 96-bit clock is input to SQCK, 96 bits of data are output to SQSO.
The initial 80 bits are Sub-Q data (see "§2. Subcode Interface"). The last 16 bits are LSB first, and consist of
15-bit PCM data (absolute values) and an L/R flag.
The final bit (L/R flag) is high when the PCM data is from the left channel and low when the data is from the
right channel.
The PCM data is reset and the L/R flag is reversed after one readout.
Then the maximum value is measured until the next readout.
Command bit
VARION = 0
Processing
Variable pitch mode is off. (The internal clock uses the crystal reference.)
Variable pitch mode is on. (The internal clock uses the VCO2 reference.)
VARION = 1
Command bit
VARIUSE = 0
Processing
Set VARIUSE = 0 when not using variable pitch mode.
Set VARIUSE = 1 when using variable pitch mode.
See "$DX commands" for the variable pitch range and example of use.
VARIUSE = 1
