processor communication, and 32 semaphore reg-
isters are used for resource locking. Three timers
are available for general-purpose functions, as well
as more specialized functions, such as watchdog
timers and performance monitoring.
The large number of general purpose I/Os offers
flexibility in system configurations. Three separate
synchronous serial interfaces, conforming to indus-
try-standard protocols, are available for a variety of
system interface functions. Four general purpose
software interrupts and twelve hardware interrupts
help reduce peripheral overhead and improve UI
responsiveness. Power-down control of the internal
clocks is also possible. An internal PLL is used to
generate the internal system and memory clocks as
well as audio clocks for all supported sample rates.

Decoded audio data is written into an output FIFO
in 16-, 18-, 20- or 24-bit PCM format. A flexible
audio output stage can simultaneously output 4
Audio Output
channels of PCM data to external audio DACs, plus
an independent IEC-958 encoded output. The IEC-
958 output has fully programmable channel status
(commercial), and provides a flexible solution to
support all IEC-958 modes for user data. The audio
output circuit contains an auto-mute detect circuit,
which can generate internal or external mute con-
trols
PCM FIFO data up to 18 bits can also be output by
the on-board sigma-delta stereo modulator. The
sigma-delta modulator yields a typical 85 dB sig-
nal-to-noise ratio with few external components re-
quired, resulting in a low-cost, low parts count
analog front end. The modulator has a 32x upsam-
pling filter, followed by a 32x interpolator, and fi-
nally a 5
th
-order Sigma-Delta modulator. The
auto-mute circuit also works on the modulator out-
put, and there are separate programmable attenua-
tors for the modulator output and both PCM
outputs.
