Universal Serial Bus (USB)

The value in the RFMR can be used to determine approximately how much time has elapsed since the USB
host sent its last start-of-frame packet.
Because the hardware does not guarantee that any of the bit values are stable during the read access:

only the higher-order bits should be used
the returned data should always be de-glitched by verifying that the same value is seen on the
higher-order bits for two consecutive read cycles.

Real-time frame count. Contains the current USB frame counter value. The counter is incremented one
time for every USB bit time and is reset when a SOF packet from the host is detected or an artificial start
of frame (ASOF) interrupt is generated.
