The AT91SAM9M10 product features 5 PIO controllers, PIOA, PIOB, PIOC, PIOD and PIOE, which mul-
tiplex the I/O lines of the peripheral set. Each PIO Controller controls up to 32 lines. Each line can be 
assigned to one of two peripheral functions, A or B. The multiplexing tables in the following paragraphs 
define how the I/O lines of peripherals A and B are multiplexed on the PIO Controllers.

"R.Select" = connection selectable via an on-board resistor (default not populated)
