IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital signal with the
sampling frequency undefined (neither 44.1k, 32k nor 48k). Since the operation of each device cannot be
assured at fs outside specifications, the sub-microprocessor handles this status as the forced analog mode
(ignored even if decoding is OK from the detection terminal level), and selects the signal from the analog input
terminal. Since the sub-microprocessor transmits 000B (analog) for STATUS#0 bits 4-6 to the main
microprocessor, the main microprocessor visually operates in the same way as with digital unlocking.
