A hardware reset is issued by forcing the RESETB pin to logic low. The RESETB input pin resets all framers, LIUs,
and BERTs. Note that not all registers are cleared to 00h on a reset condition. The register space must be
reinitialized to appropriate values after a hardware or software reset has occurred. This includes writing
reserved locations to 00h.

The DS26514 has several features included to reduce power consumption. The individual LIU transmitters can be
powered down by setting the TPDE bit in the LIU Maintenance Control Register (LMCR). Note that powering down
the transmit LIU results in a high-impedance state for the corresponding TTIPn and TRINGn pins and reduced
operating current. The RPDE in the
The TE (transmit enable) bit in the
them in a high-impedance mode, while keeping the LIU in an active state (powered up). This is useful for
equipment protection-switching applications.
