10. HARDWARE MODE
The CS8415A has a hardware mode which allows
using the device without a microcontroller. Hard-
ware mode is selected by connecting the H/S pin to
VL+. Various pins change function in hardware
mode, described in the hardware mode pin defini-
tion section.
Hardware mode data flow is shown in Figure 11.
Audio data is input through the AES3 receiver, and
routed to 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 at both edges of OLRCK
(master mode only, see Figure 9).

The current audio sample is passed unmodified to
the serial audio output port if the validity bit is
high, or a parity, bi-phase, or PLL lock error oc-
curs.
10.1 Serial Audio Port Formats
In hardware mode, only a limited number of alter-
native serial audio port formats are available.
Table 3 defines the equivalent software mode bit
settings for each format.
Start-up options are shown in Table 4, and allow
choice of the serial audio output port as a master or
slave, and the serial audio port format.
Serial Output Port is Master
Serial Output Port is Slave
