* From TRM page 15-105:
*
* Under certain conditions, some read and write access to the FX2
* registers must be separated by a "synchronization delay". The
* delay is necessary only under the following conditions:
*
* - between a write to any register in the 0xE600 - 0xE6FF range
* and a write to one of the registers listed below.
*
* - between a write to one of the registers listed below and a read
* from any register in the 0xE600 - 0xE6FF range.

* Registers which require a synchronization delay:
*
* FIFORESET FIFOPINPOLAR
* INPKTEND EPxBCH:L
* EPxFIFOPFH:L EPxAUTOINLENH:L
* EPxFIFOCFG EPxGPIFFLGSEL
