Serial NAND Configuration Fields table shows configuration pins assignment to functions when boot mode is Serial NAND.
BOOTMODE Pins | Field | Value | Description |
---|---|---|---|
8 | Read Mode 2 | 0 | Reserved (Read mode is taken from Read Mode 1 |
1 | SPI/ 1-1-1 mode (Read mode is taken from Read Mode 2 and Read Mode 1 is ignored) | ||
7 | Read Mode 1 | 0 | OSPI/ 1-1-8 Mode (valid only when Read Mode 2 is 0) |
1 | OSPI/ 1-1-4 Mode (valid only when Read Mode 2 is 0) |
