27.6 Interrupt
Sources
The FLCTL has six interrupt sources: Status error, ready/busy timeout error, ECC error, transfer
end, FIFO0 transfer request, and FIFO1 transfer request. Each of the interrupt sources has its
corresponding interrupt flag and the interrupt can be requested independently to the CPU if the
interrupt is enabled by the interrupt enable bit. Note that the status error and ready/busy timeout
error use the common FLSTE interrupt to the CPU.

Note: Flags for the FIFO0 overrun error/underrun error and FIFO1 overrun error/underrun error
also exist. However, no interrupt is requested to the CPU.

DMA Transfer Specifications
The FLCTL can request DMA transfers separately to the data area FLDTFIFO and control code
area FLECFIFO. Table 27.6 summarizes DMA transfer enable or disable states in each access
mode.
