STK311-020
Control Input CORR. SEL Read Timing
Normally, this pin is checked for its state. However, error
correction can be enabled/disabled at any time.
During Sync Detection
CORR. SEL is read for every bit of demodulator data from
the RDS demodulator IC (indiated by ), and is read into
the LSI when 4 consecutive, matching states occur.

After Sync Detection
CORR. SEL is read for the head of each block of demodula-
tor data from the RDS demodulator IC (indiated by ), and
is read into the LSI when 4 consecutive, matching states
occur.
