27. NAND Flash Memory Controller (FLCTL)
27.6
The FLCTL has four interrupt sources. Each of the interrupt sources has its corresponding
interrupt flag. The interrupt request is generated independently if the interrupt is enabled by the
interrupt enable bit. The status error and ready/busy timeout error use the common FLSTE
interrupt.
Table 27.6 FLCTL Interrupt Requests
27.7
The FLCTL can request DMA transfers separately to the data sector, FLDTFIFO, and control
code sector, FLECFIFO. Table 27.7 shows whether DMA transfer is enabled or disabled in each
access mode.
Table 27.7 DMA Transfer Settings
For details on DMAC settings, see section 14, Direct Memory Access Controller (DMAC).
