Class Members
uint64_t	__pad0__: 1
TriggerMode	trigger_mode: 1	Generate edge or level triggered interrupts.
uint64_t	interrupt_status: 1	Enable (`1`) or disable (`0`) interrupts.
ComparatorMode	comparator_mode: 1	periodic or one shot mode
uint64_t	periodic_capable: 1	Is timer capable of periodic mode (read-only)
CounterSize	counter_size: 1	32- or 64bit size (read-only)
uint64_t	set_value: 1	if set to 1, the accumulator can be set in software
uint64_t	__pad1__: 1
uint64_t	small_mode: 1	if set to 1 while supporting 64bit size, the timer runs in 32-bit mode
uint64_t	ioapic_slot: 5	I/O-APIC slot (must be set in mask `supported_ioapic_slots`)
uint64_t	fsb_interrupt_enabled: 1	if set to 1, the timer will use FSB interrupt mapping
uint64_t	fsb_interrupt_delivery: 1	if set to 1, the timer supports FSB interrupt mapping (read-only)
uint64_t	__pad2__: 16
uint64_t	supported_ioapic_slots: 32	bit mask containing the supported I/O APIC slots (read-only)
