14.4.8.1. MAP00 Commands

MAP00 commands access a page buffer in the NAND flash device. Addressing always begins at 0x0 and extends to the page size specified by the device_main_area_size and device_spare_area_size registers in the config group. You can use this command to perform a boot read. Use MAP00 commands in read‑modify‑write (RMW) operations to read or write any word in the buffer. MAP00 commands allow a direct data path to the page buffer in the device.

The host can access the page buffer directly using the MAP00 commands only if there are no other MAP01 or MAP10 commands active on the NAND flash controller.
