Table 5-10 shows configuration pins assignment to functions when boot mode is QSPI using the OSPI module. The BOOTMODE pin corresponding to the Iclk field determines the setting for LOOPCLK_SEL bit field in CTRLMMR_OSPI0_CLKSEL register
BOOTMODE Pins | Field | Value | Description |
---|---|---|---|
8 | Iclk | 0 | Iclock source external |
1 | Iclock source internal (pad loopback) | ||
7 | Csel | 0 | Boot Flash is on CS 0 |
1 | Boot Flash is on CS 1 |
Table 5-11 summarizes the OSPI pin configuration done by ROM code for QSPI boot device on port 0.
