Interrupt
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 func-
tions to HSMCI pins.
Table 36-2.
The HSMCI is clocked through the Power Management Controller (PMC), so the programmer
must first configure the PMC to enable the HSMCI clock.
The HSMCI interface has an interrupt line connected to the Advanced Interrupt Controller (AIC).
Handling the HSMCI interrupt requires programming the AIC before configuring the HSMCI.
