Communication to DSP TMS320C26 in
Free-Run
To use free-run mode the chip select on the
SP8531
must be low and is therefore tied to
ground. Since status gives a low pulse before the
start of conversion, this signal is used to provide
the necessary Frame Sync Receive (FSR) pulse
to start reading the data. All it needs is an
inverter to provide for the correct logic level.

TMS320C26
The Data Out (Dout) can be connected directly
to the Data Receive (DR) of the DSP and both
elements use the same externally provided clock.
The minimal hold time for DR after falling edge
of CLKR is 20ns where the typical hold time for
the
SP8531
is 50ns making the data read valid.
Note that although the
SP8531
is essentially a
12 bit converter, it sends 16 bits with the four
MSB’s as zero’s.
