Abstract
An integrated circuit contains circuitry to operate in such a fashion to reduce output noise when switching output circuits from a programming mode to a user mode. In an implementation, the integrated circuit (125) is configurable in the programming mode with user configuration data. In the user mode, the integrated circuit will operate with the functionality as defined by the user during the programming mode. When switching from the programming mode to the user mode, each output (210) of the integrated circuit will switch to its user mode value. In order to minimize switching noise, the outputs are released to their user mode values not all at the same time.
