Multichannel Buffered Serial Port (McBSP) Module

The McBSP module has the following features:

  • Compatible to McBSP in TMS320C54x/TMS320C55x 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 A/D and 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,
  • TMS320F28335 TMS320F28334 TMS320F28333 TMS320F28332 TMS320F28235 TMS320F28234 TMS320F28232 q1_prs439.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 5 for maximum I/O pin toggling speed.

Figure 6-11 shows the block diagram of the McBSP module.
