The SMC supports asynchronous burst reads in page mode, providing that the page mode is
enabled in the MODE register (PMEN field). The page size must be configured in the MODE
register (PS field) to 4, 8, 16 or 32 bytes.
The page defines a set of consecutive bytes into memory. A 4-byte page (resp. 8-, 16-, 32-byte
page) is always aligned to 4-byte boundaries (resp. 8-, 16-, 32-byte boundaries) of memory. The
MSB of data address defines the address of the page in memory, the LSB of address define the
address of the data in the page as detailed in
With page mode memory devices, the first access to one page (t
quent accesses to the page (t
enables the user to define different read timings for the first access within one page, and next
accesses within the page.
