Indicates the armed/disarmed status of each alarm. A write to the corresponding ALARMx register arms the alarm. Alarms automatically disarm upon firing, but writing ones here will disarm immediately without waiting to fire.
Selects the source for the timer. Defaults to the normal tick configured in the ticks block (typically configured to 1 microsecond). Writing to 1 will ignore the tick and count clk_sys cycles instead.
