Flash Page Size.
The SMC_B2CTL.PGSZ bits select the flash page size, if page flash or sync burst
flash protocol has been enabled (SMC_B2CTL.MODE > 1). Note that the
SMC_B2CTL.PGSZ bits must be set to match the flash protocol of the external flash
memory device in the system. The typical SMC_B2CTL.PGSZ selection for external
devices supporting async flash or async flash page protocols is 4 or 8 words. The typi-
cal SMC_B2CTL.PGSZ selection for external devices supporting sync burst flash pro-
tocol is 16 words.
