3.1.1.3. Dynamic OCT

Dynamic OCT is useful for terminating a high-performance bidirectional path by optimizing signal integrity depending on the direction of the data. Dynamic OCT also helps save power because termination switches on only during input operation and thus draws less static power.

Table 38.  Dynamic OCT Based on Bidirectional I/ODynamic RT OCT or RS OCT is enabled or disabled based on whether the bidirectional I/O acts as a receiver or driver.
Dynamic OCT Bidirectional I/O State
