Abstract: Disclosed is a voltage regulator circuit configured to selectively operate the voltage regulator circuit in a first mode of operation and a second mode of operation. The voltage regulator can change operation of the voltage regulator circuit between the first mode of operation to the second mode of operation in response to a change in a sensed load condition of the voltage regulator circuit. The voltage regulator can change operation from the second mode of operation to the first mode of operation in response to the sensed load condition changing from the second load condition to the first load condition, but only when the sensed load condition has not changed in a given direction between the first load condition and the second load condition for at least a predetermined period of time T.

Abstract: Communication channels among a connector port module, a debug interface module, and a power communication interface module may be established. Each of these elements may be part of a system-on-chip. The power communication interface module may be coupled to an integrated circuit, such as a power management integrated circuit. The connector port module may be coupled to a connector, in which the connector may facilitate connections between the PCD and one or more external devices, such as a testing/debugging device. The connector may comprise an SD connector. The connector may be monitored for a device present signal. If a device present signal has been detected, then it may be determined if a valid access code has been received for allowing access to communications within the PCD. If a valid access code is received, then a command may be issued to relinquish control of the integrated circuit from a master processor.
