Access:
• MICRO_FRAME_NUM: Microframe Number
Number of the received microframe (0 to 7) in one frame.This field is reset at the beginning of each new frame (1 ms).
One microframe is received each 125 microseconds (1 ms/8).
• FRAME_NUMBER: Frame Number as defined in the Packet Field Formats
This field is provided in the last received SOF packet (see INT_SOF in the
• FNUM_ERR: Frame Number CRC Error
This bit is set by hardware when a corrupted Frame Number in Start of Frame packet (or Micro SOF) is received.
This bit and the INT_SOF (or MICRO_SOF) interrupt are updated at the same time.
