RAM Allocation in the FX2 vs. FX
The FX (and EZ-USB) isochronous buffers were located at 0x2000-0x2800. The FX2 does not seem to have implemented RAM in this area. For a stand-alone application, the total amount of RAM (internal) is insufficient. Disabling the ISO endpoints made an extra 2K RAM available. Does the FX2 have any options as this?
Switching IFCLK source in SX2.
Can the IFCONFIG be set to synchronous (with a driven external IFCLK pin) on power up or is it necessary to have the device first power up in asynchronous mode and then switch to synchronous? What should one be aware of while switching from asynchronous to synchronous ?
