Description
• Determines the output of the IFSW output port and controls the muting function.
Data = 0: Receive mode
= 1: Muted
• Determines the output of the BDSW output port and switches the reception band.
Data = 0: AM
= 1: FM
• Determines the output of the DO pin.

ΠCount start
 Count end _{Ž CE : HI}
(1) If the end-UC setting is used, the DO pin will automatically go to the open state when an
IF count operation starts (CTE transitions from 0 to 1).
(2) When the IF counter measurement completes, the DO pin goes low and it becomes
possible to check for the count completed state.
(3) The DO pin goes to the open state when serial data I/O is performed (when the CE pin is
high).
Note: The DO pin goes to the open state during the data input period (IN1 and IN2 modes
when CE is high), regardless of the values of the DO pin control data (DOC0:2). During
the data output period (OUT mode when CE is high), the DO pin outputs the content of
the internal DO serial data in synchronization with the CL signal, regardless of the
values of the DO pin control data (DOC0:2).
