... so that the pin keeps the inactive state of the CSN line when it is not controlled by the QSPI peripheral and the driver is not suspended. Currently, the nrf_qspi_nor shim deinitializes the nrfx_qspi driver after each operation, what leaves the pin uncontrolled until a new operation is requested (and the nrfx_qspi driver is initialized again) or the driver is suspended (and the pin is put into low-power state). This can cause the flash chip to needlessly consume current when there is no pull-up resistor on its CSN line and the line appears active. Prevent this by keeping the pin in a defined (inactive) state. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no> |
