Enumerating SX2 in FULL Speed mode

Last Updated: June 10, 2011

How can I force the SX2 to enumerate in full speed mode only?


The SX2 can be set to run in full speed only mode. To force full speed only enumeration write a   0x02 to the unindexed register CT1 at address 0xE6FB before downloading the descriptors. This disables the chirp mechanism forcing the SX2 to come up in full speed only mode after the descriptors are loaded. The methos of writing to the SX2 registers has been described in the SX2 datasheet.
