I/O Lines Description
In order to use this module, other parts of the system must be configured correctly, as described
below.
If the CPU enters a sleep mode that disables clocks used by the MCI, the MCI will stop function-
ing and resume operation after the system wakes up from sleep mode.
The pins used for interfacing the MultiMedia Cards or SD Cards may be multiplexed with GPIO
lines. User must first program the I/O controller to assign the peripheral functions to MCI pins.
The clock for the MCI bus interface (CLK_MCI) is generated by the Power Manager. This clock
is enabled at reset, and can be disabled in the Power Manager. It is recommended to disable the
MCI before disabling the clock, to avoid freezing the MCI in an undefined state.
The MCI interrupt request line is connected to the interrupt controller. Using the MCI interrupt
requires the interrupt controller to be programmed first.
