MICROPROCESSOR INTERFACING
The serial interface on the AD7262/AD7262-5 allows the parts
to be directly connected to a range of different microprocessors.
This section explains how to interface the AD7262/AD7262-5
with the Analog Devices, Inc., Blackfin DSP, the ADSP-BF537.
AD7262/AD7262-5 TO ADSP-BF53x
The ADSP-BF53x family of DSPs interface directly to the
AD7262/AD7262-5 without any glue logic required. The
VDRIVE pin of the AD7262/AD7262-5 takes the same supply
voltage as that of the ADSP-BF53x. This allows the ADC to
operate at a higher supply voltage than its serial interface and,
therefore, the ADSP-BF53x, if necessary. The availability of
secondary receive registers on the serial ports of the Blackfin
DSPs means only one serial port is necessary to read from both
DOUT pins simultaneously. Figure 37 shows both DOUTA and
DOUTB of the AD7262/AD7262-5 connected to Serial Port 0 of
the ADSP-BF53x. The SPORT0 Receive Configuration 1
register and SPORT0 Receive Configuration 2 register should
be set up as outlined in Table 14 and Table 15.
