Function
the first frame of the tributary multiframe in each
STM-1 within the STM-4 (OD[7:0]) stream.
OTMF[1] is selectable to pulse high during the
third byte after J1 of the first STS-1 in each
STM-1 or during the H4 byte of the path
overhead which indicates that the next frame is
the first frame of the tributary multiframe.
Selection between marking the third byte after
each J1 or H4 bytes is controlled by the
corresponding OTMFH4 register bit. Pulses on
OTMF[1] are only effective during the H4 or third
byte after each J1 byte positions, as appropriate.
OTMF[1] is ignored at other byte positions.
OTMF[1] is sampled on the rising edge of
HSCLK.
