Abstract

A programmable system includes an input/output (I/O) pin that is configurable into multiple operational states. The programmable system further includes a memory device to store configuration data that, when provided to the I/O pin, causes the I/O pin to reconfigure into one of the operational states. When power is supplied to the system, the memory device is configured to provide the configuration data to the I/O pin prior to a system microcontroller becoming operational responsive to the power.
