| inherit(vsf_peripheral_capability_t) uint8_t is_async uint8_t | support_output_and_set: 1 |
| Flag indicating if GPIO operations are asynchronous. When set, operations are only guaranteed to be sequential when operating on the same port consecutively. When used with different ports, operations on pins may not be sequential. | |
| uint8_t | support_output_and_clear: 1 |
| Support for atomic output and clear operations. Prevents signal glitches when switching from input to output mode. | |
| uint8_t | support_interrupt: 1 |
| Support for external interrupt functionality. When set, the GPIO pins can be configured to generate interrupts. | |
| uint8_t | pin_count |
| Total number of pins in hardware. Includes all pins, even those that cannot be configured as GPIO. If some pins cannot be used as GPIO, the corresponding bit in pin_mask is 0. | |
| vsf_gpio_pin_mask_t | pin_mask |
| Available pin mask indicating which pins can be used as GPIO. Common bit patterns include: | |
