Abstract
A programmable logic device (PLD) adapted to enter a low-power or sleep mode with programmable wakeup pins in a wakeup group of pins is disclosed. Wake on a single pin change, wake on vector, and wake on a single pin transition are supported. The approach is to select the actively participating pins, enable the desired operation, define the wakeup condition, enter sleep mode, monitor the external signals coupled to the active pins, and exit sleep mode when the wakeup condition is detected.
