Interrupt
The SMC has an interrupt line connected to the Nested Vector Interrupt Controller (NVIC). Han-
dling the SMC interrupt requires programming the NVIC before configuring the SMC.
Table 26-3.
Table 26-4.
Note:
The SMC provides up to 24 address lines, A[23:0]. This allows each chip select line to address
up to 16 Mbytes of memory.
If the physical memory device connected on one chip select is smaller than 16 Mbytes, it wraps
around and appears to be repeated within this space. The SMC correctly handles any valid
access to the memory device within the page (see
A[23:0] is only significant for 8-bit memory, A[23:1] is used for 16-bit memory.
