(8) RDS/RBDS (MMBS) selection (1 bit): RM
Initial value: RM = 0
—: Open, q
q, q: Output enabled (q = reverse polarity)
Initial values: PT0 = 1, PT1 = 1, PT2 = 0 (mode 3)
Caution: 1. When PT2 is set to 1, the polarity of the T3 (RDCL), T6 (ERROR/57K), T7 (CORREC/ARI-ID) SYNC, and RDS-ID pins changes to active
high.
2. The output pins (T3 to T7, SYNC, and RDS-ID) are all open-drain pins, and require external pull-up resistors to output data.
These pins indicate the number of blocks in a set of 48 blocks that had errors before correction. The output polarity of these pins is fixed at the values
listed in the table.

RBDS support
Decoding method
0
None
Only RDS data is decoded correctly (Offset word E is not detected.)
1
Provided
RDS and MMBS data is decoded correctly (Offset word E is also detected.)
(9) Output pin settings (3 bits): PT0 to PT2
These bits control the T3, T4, T5, T6, T7, SYNC, and RDS-ID pins.
