Detailed Description

headerfile for usbpdi_common.c

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 PINFLAGSAB PINFLAGSCD EPxFIFOIE EPxFIFOIRQ GPIFIE GPIFIRQ UDMACRCH:L GPIFADRH:L GPIFTRIG EPxGPIFTRIG OUTPKTEND REVCTL GPIFTCB3 GPIFTCB2 GPIFTCB1 GPIFTCB0
