15.4.8.2.2. MAP01 Usage Limitations

Use the MAP01 command as follows:
  • A complete page must be read or written using a MAP01 command. During such transfers, every transaction from the host must have the same block and page address. The NAND flash controller internally keeps track of how much data it reads or writes.
  • MAP00 commands cannot be used in between using MAP01 commands for reading or writing a page.
  • DMA must be disabled (the flag bit of the dma_enable register in the dma group must be set to 0) while the host is performing MAP01 operations directly. If the host issues MAP01 commands to the NAND flash controller while DMA is enabled, the flash controller discards the request and generates an unsup_cmd interrupt.
