HcFmNumber register (address: value read from func0 or func1 of address
10H
+
3CH)
This register is a 16-bit counter, and the bit allocation is given in
Table 72
. It provides
a timing reference among events happening in the Host Controller and the HCD. The
HCD may use the 16-bit value specified in this register and generate a 32-bit frame
number without requiring frequent access to the register.

Description
FRT
FrameRemainingToggle:
This bit is loaded from the FIT
(FrameIntervalToggle) field of HcFmInterval whenever FR
(FrameRemaining) reaches 0. This bit is used by the HCD for the
synchronization between FI (FrameInterval) and FR.

FR[13:0]
FrameRemaining:
This counter is decremented at each bit time.
When it reaches 0, it is reset by loading the FI value specified in
HcFmInterval at the next bit time boundary. When entering the
USBOPERATIONAL state, the Host Controller re-loads the content
with the FI of HcFmInterval and uses the updated value from the
next SOF.
