DSP Interface to the TMS320C54_
The MAX1277/MAX1279 can be directly connected
to the TMS320C54_ family of DSPs from Texas
Instruments, Inc. Set the DSP to generate its own
clocks or use external clock signals. Use either the
standard or buffered serial port. Figure 15 shows the
simplest interface between the MAX1277/MAX1279 and
the TMS320C54_, where the transmit serial clock
(CLKX) drives the receive serial clock (CLKR) and
SCLK, and the transmit frame sync (FSX) drives the
receive frame sync (FSR) and CNVST.
For continuous conversion, set the serial port to trans-
mit a clock, and pulse the frame sync signal for a clock
period before data transmission. The serial-port config-
uration (SPC) register should be set up with internal
frame sync (TXM = 1), CLKX driven by an on-chip clock
source (MCM = 1), burst mode (FSM = 1), and 16-bit
word length (FO = 0).
This setup allows continuous conversions provided that
the data transmit register (DXR) and the data-receive
register (DRR) are serviced before the next conversion.
Alternatively, autobuffering can be enabled when using
the buffered serial port to execute conversions and
