Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Bit | Name | Description | Access | Reset |
---|---|---|---|---|
28 | issue_read_before_sync |
Issue LOAD cmd to flash core even if SYNC condition is not satisfied. But the data is read from the device (for this load) only after the SYNC condition has been satisfied. If this value is 0, CMD DMA waits for SYNC before issuing a READ command. This bit should be set to 0 if the controller is being accessed in non-Command DMA mode. |
RW | 0x0 |
24 | update_sync_before_prog_comp |
Update SYNC Pointer after the data is written to flash and dont wait for program to complete. If this value is 0, CMD DMA waits for page program to get over before updating the sync pointer. This bit should be set to 0 if the controller is being accessed in non-Command DMA mode. |
RW | 0x0 |
3:0 | value |
Indicates the first block of next LUN. This information is used for extracting the target LUN during LUN interleaving. After Initialization, if the controller detects an ONFi device, this field is automatically updated by the controller. For other devices, software will need to write to this register for proper interleaving. The value in this register is interpreted as follows- [list][*]0 - Next LUN starts from 1024. [*]1 - Next LUN starts from 2048. [*]2 - Next LUN starts from 4096 and so on... [/list] |
