CPU Registers
This LSI has both write registers and read registers. Access to the registers is made via CCB IF or parallel IF. Switching
of access mode is made with the SP pin. (CCB IF: SP=H, Parallel IF: SP=L)
(1) Write registers
Setting any data to ‘0h’ or ‘7h’ or larger address of Write-registers is prohibited. Do not set any data to these addresses.

When the block synchronization determination output (BLOCK) is to be used determination of whether or not there is
any FM multiplex data, it is recommended to set the allowable number of BIC errors during backward protection to
‘0001b’ or ‘0000b’.
