Note 11: At a reset, the initial values are D1 = D0 = 0H.
Note 12: A reset or a boot command sets the coefficient RAM value to its initial value.
Note 13: A reset or a boot command sets the offset RAM value to its initial value.

amount of key shift.
address consists of three memory allocation bits, three decimation rate bits, and 2 offset address bits.
Because the content of these settings depends on the internal program, refer to the separate software

Command to set the output data of the extended output port by adding two-byte data.
The two-byte data are output in parallel directly from the EXT0 to EXTF pins.
The command is used to control the LEDs which display the key control on/off status and the
Command to write coefficient RAM data by adding three-byte data.
As in the following table, the value of the MSB of the address is assigned to the LSB of the CL bits.
The R/W offset addresses of coefficient RAM and delay RAM are written as 8 bits of data. An
