DELETE
The DELETE command is used to delete the voice in the specified voice number.
In the DELETE command, the bit-15 ~ bit-10 is 000100 in binary, and the bit-9 ~ bit-0 is the
voice number in binary. Up to 1024 voice numbers user can specify.
After the DELETE command sent, the /BUSY pin will be drove low to indicate the delete
operation starting. When delete operation is finished, the /BUSY pin will be released.
The memory space in the specified voice number will be release after delete operation, user
can get more free space by delete unused voice.
