Note

1. Shaded areas: PERR#, REQ[4,5]#, GNT[4,5]#, HL[11], SUSCLK, ALERTCLK, and ALERTDATA are ICH

(82801AA) Signals only. The associated GPIOx signals are multiplexed on the ICH and are

non-multiplexed on ICH0.

2. General Purpose I/O Unit. Some GPIO signals are multiplexed with signals in other functional units.
