support_output_and_set

inherit (vsf_peripheral_capability_t) uint8_t is_async uint8_t vsf_gpio_capability_t::support_output_and_set

To avoid bumps when converting from input to output.

Asynchronous GPIO they are only guaranteed to be sequential when operating the current port consecutively.

When they are used together with other ports, they are not guaranteed to be sequential for the operation of the pins of different ports.

support_output_and_clear

uint8_t vsf_gpio_capability_t::support_output_and_clear

support_interrupt

uint8_t vsf_gpio_capability_t::support_interrupt

supports external interrupts

pin_count

uint8_t vsf_gpio_capability_t::pin_count

total number of pins of hardware, even if some pins cannot be configured as GPIO. if some of the pins cannot be used as GPIO,the corresponding bit in pin_mask is 0, otherwise is 1.

pin_mask

vsf_gpio_pin_mask_t vsf_gpio_capability_t::pin_mask

available pin mask may be: 0x000000FF (8 pins), 0x0000FFFF (16 pins), 0xFFFFFFFF (32 pins), 0xFFFFFFFE (31 pins, PIN0 is not available)
