An integrated circuit (20) configures the active level of an input, output, or input/output pin by sensing a logic state on the pin's bonding pad (21) at the inactivation of a reset signal, such as a power-on reset signal. The integrated circuit (20) selects a true or complement signal to provide to...http://www.google.com.hk/patents/US5414380?utm_source=gb-gplus-share專利 US5414380 - Integrated circuit with an active-level configurable and method therefor
