3.16 EXTO Command
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
amount of key shift.

Note 11: At a reset, the initial values are D1 D0 0H.
3.17 CRAM Command
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.

Note 12: A reset or a boot command sets the coefficient RAM value to its initial value.
The R/W offset addresses of coefficient RAM and delay RAM are written as
1
8 bits of data. An
address consists of three memory allocation bits, three decimation rate bits, and
1
2 offset address bits.
Because the content of these settings depends on the internal program, refer to the separate software
datasheet.
