Abstract

A suspend mode is provided that can be asserted using an Internal Configuration Access Port (ICAP) of an integrated circuit such as a Field Programmable Gate Array (FPGA), as supposed to a dedicated external suspend pin typically accessed by a device external to the FPGA. The ICAP is designed to assert the suspend mode through a configuration block to maintain the state of the configuration memory array while lowering power, in a similar manner to when an external suspend pin is accessed. Internal circuits can, thus, be used to assert a suspend mode through the ICAP.
