Figure 33. Operational Diagram
QSPI Interface
The AS1532/AS1533 can interface with QSPI using the circuit in
Figure 34
(f
SCLK
= 4.0MHz, CPOL = 0, CPHA = 0).
This QSPI circuit can be programmed to do a conversion on each of the four channels. The result is stored in memory
without affecting CPU performance, since QSPI incorporates a micro-sequencer.
