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, which are 15-
bit PCM data (absolute values) and an L/R flag.
The L/R flag is high when the 15-bit 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 maximum value measuring continues until the next readout.
Command bit
VARION = 0
Processing
Variable pitch mode is turned off. (The crystal is the reference to the internal clock.)
Variable pitch mode is turned on. (The VCO2 is the reference to the internal clock.)
VARION = 1
Command bit
VARIUSE = 0
Processing
When the variable pitch mode is not used, set VARIUSE to 0 .
When the variable pitch mode is used, set VARIUSE to 1.
∗
See "$DX commands" for the variable range and the usage example of the variable pitch.
VARIUSE = 1
