SGUS062A –JUNE 2009 –REVISED APRIL 2010

4.5Multichannel 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

where CLKSRG source could be LSPCLK, CLKX, or CLKR.(2)

(2)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.
