Hi Liang,
1. The definitions given in the C6670 datasheet (SPRS689D) are correct i.e. VCPAXEVT is 11 and VCPAREVT is 10. The values in the VCP2 user guide (SPRUGV6A) appear to have been left from legacy devices and are incorrect. We will update the VCP2 user guide to resolve this issue. Thanks for bringing this error to our notice and in the meantime please refer to the corresponding device datasheet for the correct event definitions.
2. For the second problem, I would request you to send your test project along-with the instructions to build it to help us look into the issue. Thanks.
Regards
