are controlled by data input/output of SD, SI and SO pins and by CMD, CS and WR control pins.
transfers data of the TMP register to the register of each command function and executes data by
executing the command.

9. Command Data and Subcommand Data
In parallel input, command data and subcommand data are controlled by the data bus of D7-D0
This LSI reads data to the internal register (TMP register) by executing the subcommand, and
A subcommand and command are distinguished by the level of the CMD pin. “H” level indicates

Starts playback of the channel for which data stored in the register is "H".
Stops playback of channel for which data stored in the register is "H".
Repeats playback of channel for which data stored in the regiter is "H".
Changes option by command.
Inserts silence corresponding to the length of data stored in the register.
Transfers phrase address stored in the register to the phrase register
of the specified channel.
This command internally transfers the 7-byte start and stop address,
the value of sampling frequency and playback algorithm which are
stored in the TMP register.
Changes volume of the specified channel to the volume of data stored
in the register.
Changes volume of the right and left D/A converter to volume of data
stored in the register.
