9.5 HC’s operational model
Upon power up, the HC Driver sets up all operational registers (32-bit). The
FSLargestDataPacket field (bits 30 to 16) of the HcFmInterval register (0DH - Read,
8DH - write) and the HcLSThreshold register (11H - Read, 91H - Write) determine the
end of the frame for full-speed and low-speed packets. By programming these fields,
the effective USB bus usage can be changed. Furthermore, the size of the ITL buffers
(HcITLBufferLength, 2AH - Read, AAH - Write) is programmed.
In the case when a USB frame contains both ISO and AT packets, two interrupts will
be generated per frame.
