35.6 Product Dependencies
35.6.1 I/O Lines
The pins used for interfacing the High Speed MultiMedia Cards or SD Cards are multiplexed with PIO lines. The
programmer must first program the PIO controllers to assign the peripheral functions to HSMCI pins.
35.6.2 Power Management
The HSMCI is clocked through the Power Management Controller (PMC), so the programmer must first configure
the PMC to enable the HSMCI clock.
35.6.3 Interrupt
The HSMCI interface has an interrupt line connected to theAdvanced Interrupt Controller (AIC) .
Handling the HSMCI interrupt requires programming theAIC before configuring the HSMCI.
