8.1 TMUX Register Descriptions
This section provides a brief description of each register bit and its functionality. The abbreviations after each regis-
ter indicate if the register is read only (RO), clear-on-read/clear-on-write (COR/COW), or read/write (R/W).
Table 87. TMUX_ID_R, TMUX Identification Register (RO)
Table 88. TMUX_ONESHOT, TMUX One-Shot Register 0 to 1 (R/W)

STS-1 Mode Control Bit.
A 1 indicates that the received
and transmitted high-speed data is STS-1 data operating
at 52 MHz. A 0 indicates that the received and transmitted
high-speed data operates at 155 MHz.
