摘要：
A pin interface for an integrated circuit. The pin interface includes logic gates for processing digital signals, and analog lines for carrying analog signals. The pin interface includes circuits for disabling the digital circuits when configured to carry analog signals. A comparator is associated with at least one of the pins for comparing the analog voltage level thereon with a reference voltage.
