This register is valid only for isochronous transfer. In other words, the register is valid status for the endpoint
that is set EPi_TYP bits to “11”.
This bit sets the storage timing of the frame number to be stored to the FRNM bits.
When this bit is set to “0”, when the SOF packet is properly received, the frame number of the received SOF
packet gets stored.
When this bit is set to “1”, when the isochronous packet transfer completes, the frame number of the properly
received SOF packet gets stored.
The frame number is stored in the FRNM with the timing set by the FMOD bit of this register. Here, the
SOFR bit is set to “1”.
