Serial Ports
The ADSP-21266 features six full duplex synchronous serial
ports that provide an inexpensive interface to a wide variety of
digital and mixed-signal peripheral devices such as the Analog
Devices AD183x family of audio codecs, ADCs, and DACs. The
serial ports are made up of two data lines, a clock, and frame
sync. The data lines can be programmed to either transmit or
receive and each data line has its own dedicated DMA channel.
Serial ports are enabled via 12 programmable and simultaneous
receive or transmit pins that support up to 24 transmit or 24
receive channels of audio data when all six SPORTs are enabled,
or six full duplex TDM streams of 128 channels per frame.
The serial ports operate at up to one-quarter of the DSP core
clock rate, providing each with a maximum data rate of
50M bits/sec for a 200 MHz core and 37.5M bits/sec for a
150 MHz core. Serial port data can be automatically transferred
to and from on-chip memory via a dedicated DMA. Each of the
serial ports can work in conjunction with another serial port to
provide TDM support. One SPORT provides two transmit sig-
nals while the other SPORT provides the two receive signals.
The frame sync and clock are shared.
Serial ports operate in four modes:
Standard DSP serial mode
Multichannel (TDM) mode
