6.2.5 Multichannel Buffered Serial Port (McBSP) Module

The McBSP module has the following features:

  • Compatible to McBSP in TMS320C54x/TMS320C55x DSP devices, except the DMA features
  • Full-duplex communication
  • Double-buffered data registers which 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
  • Support A-bis mode
  • 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
  • Two 16 x 16-level FIFO for Transmit channel
  • Two 16 x 16-level FIFO for Receive channel

The following application interfaces can be supported on the McBSP:

  • T1/E1 framers
  • MVIP switching-compatible and ST-BUS-compliant devices including:
    • MVIP framers
    • H.100 framers
    • SCSA framers
    • IOM-2 compliant devices
    • AC97-compliant devices (the necessary multiphase frame synchronization capability is provided.)
    • IIS-compliant devices
  • McBSP clock rate = CLKG = CLKSRG/(1 + CLKGDIV) , where CLKSRG source could be LSPCLK, CLKX, or CLKR. (1)
    • 1. 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—20-MHz maximum.

Figure 6-9 shows the block diagram of the McBSP module with FIFO, interfaced to the F281x version of Peripheral Frame 2.
