| gpio_transition_t | struct packed { bit transition_occurred; bit is_rising_edge; } |
structure to indicate gpio pin transition and type of transition transition_occurred: 1-yes, 0-no is_rising_edge: 1-rising edge transition, 0-falling edge transition |
| gpio_reg_update_due_t | struct packed { bit needs_update; bit [TL_DW-1:0] reg_value; time eval_time; } |
structure to indicate whether or not register update is due for particular gpio register needs_update: 1-update is due, 0-update is not due reg_value: value to be updated when update is due eval_time: time stamp of event, which triggered interrupt update |
