Peripheral Signal Multiplexing on I/O Lines

The SAM E70/S70/V70/V71 features

• Two PIO controllers on 64-pin versions (PIOA and PIOB)
• Three PIO controllers on the 100-pin version (PIOA, PIOB and PIOD)
• Five PIO controllers on the 144-pin version (PIOA, PIOB, PIOC, PIOD and PIOE), that multiplex the I/O lines of the peripheral set.

The SAM E70/S70/V70/V71 PIO Controllers control up to 32 lines and each line can be assigned to one of four peripheral functions: A, B, C or D.
