The Latte chipset includes two groups of general purpose I/O lines with interrupt capability: one common to Wood and Latte hardware (ALL) and another exclusively available to Latte (LT). Four sets of registers are provided (two for each group), and the Espresso only has access to two sets. These sets access a configurable subset of the IO pins, which the Starbuck can select.
