+ * 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
