Abstract
An apparatus includes a plurality of registers and a host interface comprising a plurality of pins. One of the plurality of registers may be a power state entry register configured to control entry to a low power state. One of the plurality of pins may be an enable pin. The apparatus may be configured to enter the low power state in response to setting the power state entry register to a first value and providing the enable pin a signal with a first level. The apparatus may be configured to exit the low power state in response to providing the enable pin the signal with a second level. The apparatus may enter an idle state after exiting the low power state. The low power state may consume less power than the idle state. The enable pin is implemented as an input configured to control a status of a plurality of regulators.
