I/O Lines Description
The pins used for interfacing the MultiMedia Cards or SD Cards may be multiplexed with PIO
lines. The programmer must first program the PIO controllers to assign the peripheral functions
to MCI pins.
The MCI may be clocked through the Power Management Controller (PMC), so the programmer
must first configure the PMC to enable the MCI clock.
