1. A device, comprising:
a circuit element coupled with a channel; and
a controller coupled with the circuit element and configured to cause the device to:
couple the channel with the circuit element, wherein the channel is in a first mode in which the channel is terminated based at least in part on coupling the channel with the circuit element, and wherein signaling over the channel in the first mode is associated with a first modulation scheme that includes three or more voltage levels to encode data communicated via the channel; and
decouple the channel from the circuit element, wherein the channel is in a second mode in which the channel is unterminated based at least in part on decoupling the channel from the circuit element, and wherein signaling over the channel in the second mode is associated with a second modulation scheme that includes fewer voltage levels to encode data communicated via the channel than the first modulation scheme.
