CONTROL REGISTER
The decoding system is controlled by reading and writing the control registers through microprocessor interface.
(/CS, SCK, SI and SO)
Note : All bits are set to “0” by initial clear (/IC=0) except for PLL0(bit 4) of PLL/DSN register (0x00).

Note : Do not write "1" into the cross-hatched bits because they are used for testing the LSI.
The following registers of address 0x18 to 0x2F are read-only (write disabled).
