*1 With SYNC_RST=1, the synchronization status and the synchronization protection status are cleared, resulting in the
unsynchronized state. This function enables rapid pull-in of frame synchronization when the frame synchronization
of new tuned and received data is deviated during tuning of a radio receiver. In this case, registers such as the
number of allowable BIC errors, the number of block forward/backward protections, and the number of frame
forward/backward protections are not initialized. During reset, the INT signal is not output and the DO pin becomes
the HI-Z output.
*2 With EC_STOP=1, all of operations and data output related to error correction is shut down. MSK demodulation,
synchronization circuits, serial data input, and layer 4 CRC circuit remain operative.
*3 With VEC_HALT=1 setting, all of LSI operation related to vertical correction and second horizontal correction are
shut down. Only the data after first horizontal correction is output.
*4 Since the output mode will be modified depending on the setting of the VEC_OUT flag or the result of horizontal
error correction, refer to the “List of operation modes” section for detail.
