Macros
PCA-Series GPIO drive strength flags
PCA-Series GPIO expander specific flags The driver flags are encoded in the 8 upper bits of gpio_dt_flags_t as follows: Bit 8-9: Drive strength for output drive strength register. Macros for configuring output drive strength, aligned with enum gpio_pca_series_drive_strength in gpio_pca_series.c. PCA_SERIES_GPIO_DRIVE_STRENGTH_X1 is the lowest strength, PCA_SERIES_GPIO_DRIVE_STRENGTH_X4 is the highest strength. Upon reset, the default drive strength is PCA_SERIES_GPIO_DRIVE_STRENGTH_X4. Note Only applies to part no with PCA_HAS_LATCH capability.
