The external memory cannot be accessed in low-power or disabled state. If a memory access is performed
an AHB error response is generated. The EMC registers can be programmed in low-power and/or disabled
state.

Chapter 5: LPC24XX External Memory Controller (EMC)
Indicates normal, or low-power mode:
Normal mode (warm reset value).
Low-power mode.
Entering low-power mode reduces memory controller
power consumption. Dynamic memory is refreshed as
necessary. The memory controller returns to normal
functional mode by clearing the low-power mode bit
(L), or by POR.
This bit must only be modified when the EMC is in idle
state.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is
not defined.
Description
This bit is used to ensure that the memory controller
enters the low-power or disabled mode cleanly by
determining if the memory controller is busy or not:
EMC is idle (warm reset value).
EMC is busy performing memory transactions,
commands, auto-refresh cycles, or is in self-refresh
mode (POR reset value).
This bit enables the EMC to enter low-power mode
or disabled mode cleanly:
Write buffers empty (POR reset value)
Write buffers contain data.
This bit indicates the operating mode of the EMC:
Normal mode
Self-refresh mode (POR reset value).
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is
not defined.
