Hardware Mode 5 Description
Hardware Mode 5 data flow is shown in
the serial audio output port. The PRO, COPY, ORIG, EMPH, and AUDIO channel status bits are output on
pins. The decoded C and U bits are also output, clocked by both edges of OLRCK (Master mode only, see
Figure
If a validity, parity, bi-phase, or lock receiver error occurs, the current audio sample is passed unmodified
to the serial audio output port.
Start-up options are shown in
and the serial audio port format. The following pages contain the detailed pin descriptions for Hardware
mode 5.
