Claim 14:
15. A tangible, non-transitory, computer-readable medium, comprising instructions that, when executed by a processor, cause an always-on timing generator to perform operations comprising:
determining that a first power supply associated with an electronic display is decoupled from a first power domain;
generating a first timing signal based on a clock signal while the first power supply is decoupled from the first power domain and image processing circuitry is operated in a reduced-power mode, wherein an additional timing generator is configured to generate a second timing signal based on the clock signal while the first power supply is coupled to the first power domain; and
transmitting a control signal to routing circuitry, wherein the control signal is configured to trigger output of the first timing signal to a display driver integrated circuit.
