| /** |
| * @brief Specifies whether XIP (execute in place) operation should be possible |
| * |
| * Normally, the driver deactivates the QSPI peripheral for periods when |
| * no QSPI operation is performed. This is done to avoid increased current |
| * consumption when the peripheral is idle. For the same reason, the base |
| * clock on nRF53 Series SoCs (HFCLK192M) is configured for those periods |
| * with the default /4 divider that cannot be used otherwise. However, when |
| * XIP accesses are used, the driver must be prevented from doing both these |
| * things as that would make XIP to fail. Hence, the application should use |
| * this function to signal to the driver that XIP accesses are expected to |
| * occur so that it keeps the QSPI peripheral operable. When XIP operation |
| * is no longer needed, it should be disabled with this function. |
| * |
| * @param dev flash device |
| * @param enable if true, the driver enables XIP operation and suppresses |
| * idle actions that would make XIP to fail |
