synchronous serial port (TMS320C203 only)
A full duplex (bidirectional 16 bit on-chip synchronous serial port provides direct communication with serial
devices such as codecs, serial A/D (analog to digital) converters, and other serial systems. The interface signals
are compatible with codecs and many other serial devices. The serial port can also be used for
intercommunication between processors in multiprocessing applications.
Both receive and transmit operations have a four deep first in first out (FIFO). The advantage of having a FIFO
is a to alleviate the CPU from being loaded with the task of servicing a transmit or receive data on every interrupt,
allowing a continuous communications stream of 16-bit data packets. The continuous mode provides operation
that once initiated requires no further frame synchronization pulses when transmitting at maximum packet
frequency. The maximum transmission rate for both transmit and receive operations is CPU divided by two or
CLKOUT1(frequency)/2. Therefore, the maximum rate at 25 ns is 20 Mbit/s and 14.28 Mbit/s at 35 ns. The serial
port is fully static and functions arbitrarily at low clocking frequencies. When the serial ports are in reset the
device can be configured to shut off the serial port internal clocks, allowing the device to run in a lower power
mode of operation.
Three signals are necessary to connect the transmit pins of the transmitting device with the receive pins of the
receiving device for data transmission. The transmitted serial data signal (DX) sends the actual data. The
transmit frame synchronization signal (FSX) initiates the transfer (at the beginning of the packet), and the
transmit clock signal (CLKX) clocks the bit transfer. The corresponding pins on the receive device are DR, FSR
and CLKR, respectively.
asynchronous serial port (’C203 only)
The asynchronous serial port is full–duplexed and transmits and receives 8-bit data only. For transmit and
receive there is one start bit and configurable one or two stop bits via the asynchronous serial port control
register (ASPCR). Double-buffering or transmit/receive data is used in all modes. Baud rate generation uses
the BRD baud rate divisor register to obtain baud rate. The maximum baud rate is 2.5 Mbit/s at 250000
characters per second (at 25 ns instruction cycle time).
TMS320C2xx scan-based emulation
TMS320C2xx devices use scan-based emulation for code- and hardware-development support. Scan-based
emulation allows the emulator to control the processor in the system without the use of intrusive cables to the
full pinout of the device.
