Frame No.
Automatic answer of this request is not supported.
According to INT_SETUP interrupt, if request received was identified as a
SYNCH_FRAME request, write 2byte data in Frame No after confirming
EP0_DSET_A bit of DATASET register is “0”. When completed, access EOP
register, and write “0” to EP0_EOPB bit, so status stage is finished. This can be
used only where the endpoint supports isochronous transfer type and supports
this request. The process is the same for a vendor request.
Please refer to vendor request section.
