Note:
The pin functionality is different according to different configurations, so the relative pin
function and name are different: the first name is relative to first configuration (L6219_HI),
the second name is relative to second configuration (L6219_8), and the third name is
relative to third and fourth configuration (L8229_0 and L8229_1).
