Register Name:
Access Type:
Reset Value:
• FNUM: Frame Number
The value contained in this register is the current SOF number.
This value can be modified by software.
• FLENHIGH: Frame Length
This register gives the 8 high-order bits of the 14-bits internal frame counter (frame counter at 12 Mhz, counter length is
12000 to ensure a SOF generation every 1 ms).
