8.5.6 Processing during error recovery
• When the preambles B, M, and W are detected, the PLL circuit goes to the locked state and data demodulation starts.
• The DATAO output data is output on the first LRCK edge after ERROR goes low.
8.6 Channel Status Data Output
8.6.1 Data delimiter bit 1 output (
8.6.2 Emphasis information output (E/INT)
• E/INT is shared by the microcontroller interface interrupt function. However, in the initial state, it outputs the
