Why do you made the the missing register definition so complicated ? The following definition would do it for your case without doing changes umpteen times across the whole usb...

@kkitayam I had a look into the code and did a quick test with the CCRX toolchain in big and little endian mode. After doing the quick hacks on the...

@kkitayam > My understanding for the current implementation (`dcd_usba`) of master branch, it supports big-endian with only CCRX. Because of using [TU_ATTR_BIT_FIELD_ORDER_BEGIN](https://github.com/hathach/tinyusb/blob/9c8c5c1c53214b8954bb28c33a496b5b423d5ecc/src/portable/renesas/usba/dcd_usba.c#L104) for endianness.
