SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
Pin Name Pin Type Pin Function
No.
TOFP
Output
40 The active high transmit outgoing frame
position (TOFP) signal is asserted once per
frame in the byte position immediately following
the Z0 bytes in the TOUT[7:0] stream. TOFP is
also used to mark the alignment of the TSUC,
TSOW, TLOW, and TAPS bit streams. TOFP is
updated on the rising edge of TICLK.
SCPO[5] Output
RDP
93 The control output (SCPO[5]) is used to control
an auxiliary device when the RDPEN bit in the
Mode Select register is set to logic 0. The
signal level on this output corresponds to the
bit value contained in the Output Port register.
The receive parity (RDP) signal indicates the
parity of the receive bus when the RDPEN bit
in the Mode Select register is set to logic 1.
The receive data bus (ROUT[7:0]]) is always
included in the parity calculation. Internal
register bits in the Mode Select register control
the inclusion of ROFP in the parity calculation,
and the sense (even/odd) of the parity. RDP is
updated on the rising edge of RICLK.

Output
94 The control port (SCPO[4:0]) together with
95
SCPO[5] provides six drive points for
controlling auxiliary devices. The signal levels
96 on this output port correspond to the bit values
97 contained in the Output Port register.
