15.HARDWARE MODE
The CS8416 has a Hardware Mode that allows the device to operate without a microcontroller. Hardware Mode is
selected by connecting the 47 k Ω pull-up/down resistor on the SDOUT pin to ground. Various pins change function
in Hardware Mode, described in
Hardware Mode data flow is shown in
to the serial audio output port. The decoded C and U bits are also output, clocked at both edges of OLRCK (master
mode only, see
An error in the incoming audio stream will be indicated on the NV/RERR pin. This pin can be configured in one of
two ways. If RERR is chosen by pulling NV/RERR to VL, the previous audio sample is held and passed to the serial
audio output port if the validity bit is high, or a parity, bi-phase, confidence or PLL lock error occurs during the current
sample. If NVERR is chosen by pulling NV/RERR to DGND, only parity, bi-phase, confidence or PLL lock error
cause the previous audio sample to be held.

Serial Audio Port Formats
In Hardware Mode, only a limited number of alternative serial audio port formats are available.

the serial audio port format.
Hardware Mode Function Selection
Hardware Mode and several options for Hardware Mode are selected by pulling CS8416 pins up to VL or
down to DGND through a 47 k Ω resistor. These settings are sensed immediately after RST is released. For
