Abstract
Externally configurable power-on-reset systems and methods for integrated circuits are disclosed that utilize internal power-on-reset circuitry and reset control circuitry to provide operational configurations determined by external connections. In one configuration where no dedicated external reset signal is desired, the reset control circuitry relies upon the internal power-one-reset circuitry to generate the internal reset control signal. In another configuration where an external reset signal is utilized, the reset control circuitry relies upon the external reset signal, which overrides the internal power-on-reset circuitry, to generate the internal reset control signal. In further configurations, the reset control circuitry utilizes logic circuitry controlled through a digital interface to determine when the internal reset control signal can be de-asserted.
