8.9.6 Multichannel Buffered Serial Port (McBSP) Module

The McBSP module has the following features:

  • Compatible to McBSP in TMS320C28x/TMS320F28x DSP devices
  • Full-duplex communication
  • Double-buffered data registers that allow a continuous data stream
  • Independent framing and clocking for receive and transmit
  • External shift clock generation or an internal programmable frequency shift clock
  • A wide selection of data sizes including 8-, 12-, 16-, 20-, 24-, or 32-bits
  • 8-bit data transfers with LSB or MSB first
  • Programmable polarity for both frame synchronization and data clocks
  • Highly programmable internal clock and frame generation
  • Direct interface to industry-standard CODECs, Analog Interface Chips (AICs), and other serially connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
  • Works with SPI-compatible devices
  • The following application interfaces can be supported on the McBSP:
    • T1/E1 framers
    • IOM-2 compliant devices
    • AC97-compliant devices (the necessary multiphase frame synchronization capability is provided.)
    • IIS-compliant devices
    • SPI
  • McBSP clock rate,
    GUID-27BFBF62-8043-4DB8-B263-02B588BADEC3-low.gif

    where CLKSRG source could be LSPCLK, CLKX, or CLKR. Serial port performance is limited by I/O buffer switching speed. Internal prescalers must be adjusted such that the peripheral speed is less than the I/O buffer speed limit.

Note:

See Section 8.9 for maximum I/O pin toggling speed.

Note:

On the 80-pin package, only the clock-stop mode (SPI) of the McBSP is supported.

Figure 8-38 shows the block diagram of the McBSP module.
