• Manufacturer Part Number: msm9810b
• Description: 8-channel Mixing Oki Adpcm Type Voice Synthesis Lsi
• Manufacturer: Oki Semiconductor

PAN Command
The PAN command adjusts the volume of the specified channel for the left and right respectively, to the volume
which corresponds to the size of data stored in the TMP register at the rise of the WR pulse.
This command enables stereo output.
When volume is controlled by the OPT command and CVOL command, volume to be output is the volume stored
in ROM multiplied by volume set by the OPT command, CVOL command, and PAN command respectively. This
volume is output from LDAO and RDAO.
Volume can be set in 16 steps up to –30 dB in –2 dB step units. Set data as shown in Table 8.
