The multichannel buffered serial port (McBSP) is based on the standard serial port
interface on the TMS320C2x, 'C3x, 'C5x, and 'C54x devices. The McBSP pro-
vides:
Full-duplex communication
Double-buffered data registers, which allow a continuous data stream
Independent framing and clocking for receive and transmit
Direct interface to industry-standard codecs, analog interface chips (AICs),
and other serially connected A/D and D/A devices
External shift clock or an internal, programmable frequency shift clock for
data transfer
Autobuffering capability through the 5-channel DMA controller
In addition, the McBSP has the following capabilities:
Direct interface to:
J
T1/E1 framers
J
MVIP switching compatible and ST-BUS compliant devices including:
H
MVIP framers
H
H.100 framers
H
SCSA framers
J
IOM-2 compliant devices
J
AC97 compliant devices. (The necessary multi phase frame synchro-
nization capability is provided.)
J
IIS compliant devices
J
SPIt devices
Multichannel transmit and receive of up to 128 channels
A wide selection of data sizes, including 8, 12, 16, 20, 24, and 32 bits
µ-Law and A-Law companding
8-bit data transfers with the option of LSB or MSB first
Programmable polarity for both frame synchronization and data clocks
Highly programmable internal clock and frame generation
