12.3.2
The following are detailed register diagrams and field descriptions.
12.3.2.1
Once every 1 ms, the USB host issues a start-of-frame packet containing a frame number. The FNR register
captures this frame number.
Table 12-3
12.3.2.2
FNMR is used to signal, via the FRM_MAT interrupt, when a particular frame number is issued by the
USB host. To avoid a false match during intermediate states of a byte write operation to the FNMR,
