value inserted depends on the value of microprocessor interface block SMPR_OH_DEFLT
bit. If SMPR_OH_DEFLT = 0, then all 0s are inserted. If SMPR_OH_DEFLT = 1, then all ones are inserted.
17.6.11 H4 Insert Control
A 4-byte sequence (0, 1, 2, and 3) will be inserted into the outgoing H4 bytes. Note that the assertion of pin TLSV1
(pin AB3) occurs after the J1 byte(s) during the frame where the H4 count equals one.
17.6.12 F3 Byte Insert
When TMUX_THSF3INS = 1
inserted into the outgoing signal. Otherwise, the associated POAC value is inserted when TMUX_TPOAC_F3 = 1

on the value of microprocessor interface block SMPR_OH_DEFLT
= 0, then all 0s are inserted. If SMPR_OH_DEFLT = 1, then all ones are inserted.
17.6.13 K3 Byte Insert
When TMUX_THSK3INS = 1
inserted into the outgoing signal. Otherwise, the associated POAC value is inserted when TMUX_TPOAC_K3 = 1
(Table 118 on page
on the value of microprocessor interface block SMPR_OH_DEFLT
0s are inserted. If SMPR_OH_DEFLT = 1, then all ones are inserted.
17.6.14 N1 Byte Insert
When TMUX_THSN1INS = 1
page
TMUX_TPOAC_N1 = 1
depends on the value of microprocessor interface block SMPR_OH_DEFLT
SMPR_OH_DEFLT = 0, then all 0s are inserted. If SMPR_OH_DEFLT = 1, then all ones are inserted.
17.6.15 MSP 1 + 1 Payload Switch
For the working transmit high-speed data output (THSDP/N, pins AF9/AE9), it is possible to select the normal
transmit path low-speed data by setting TMUX_TPSMUXSEL2 = 0
protection input data by setting TMUX_TPSMUXSEL2 = 1. Note that if the receive-side protection input is selected,
then the local clock and frame sync are generated based on the receive-side protection inputs as well.
To create the transmit high-speed protection outputs (TPSD155P/N and TPSC155P/N; pins AF13/AE13 and
AC12/AD13), it is possible to select the normal transmit path low-speed input data with TMUX_TPSMUXSEL3 = 0
(Table 106 on page
Note: Clocks and timing signals are selected by TMUX_TPSMUXSEL3 as well as the parallel data.
17.6.16 Transmit Transport Overhead Access Channel (TTOAC)
The TMUX provides a transmit transport overhead access channel (TTOAC) to provision the TOH portion of the
outgoing frame. The TTOAC channel supports three modes of operation based on values in
TMUX_TTOAC_D13MODE and TMUX_TTOAC_D412MODE
