A SPORT offers these features and capabilities:
• Provides independent transmit and receive functions.
• Transfers serial data words from 3 to 32 bits in length, either MSB
first or LSB first.
• Provides alternate framing and control for interfacing to I
devices, as well as other audio formats (for example, left-justified
stereo serial data).
• Has FIFO plus double buffered data (both receive and transmit
functions have a data buffer register and a shift register), providing
additional time to service the SPORT.
• Provides two synchronous transmit and two synchronous receive
data signals and buffers to double the total supported datastreams.
• Performs A-law and
and received words. (See
information.)
• Internally generates serial clock and frame sync signals in a wide
range of frequencies or accepts clock and frame sync input from an
external source.
• Operates with or without frame synchronization signals for each
data word, with internally generated or externally generated frame
signals, with active high or active low frame signals, and with either
of two configurable pulse widths and frame signal timing.
• Performs interrupt-driven, single word transfers to and from
on-chip memory under processor control.
