Section 24 USB Host Controller (USBH)
24.3.16 Hc Fm Number b Register (USBHFN)
USBHFN is a 16-bit counter. It indicates the reference of timing between events occurring in the
host controller and host controller driver. The host controller driver uses a 16-bit value specified in
this register and generates a 32-bit frame number without necessity for a frequent access to the
register.

Description

These bits are always read as 0. The write value should
always be 0.
Frame Number
These bits are incremented when USBHFN is reloaded.
The count will return to H'0 after H'FFFF. When the host
controller transits to the UsbOperational state, these bits
are automatically incremented. After the host controller
increments the FN bit and sends SOF in each frame
boundary, the content is written to HCCA before the host
controller reads first ED in the frame. After writing to
HCCA, the host controller sets the SF bit in USBHIS.
