AMS.ISR_{0, 1} are sticky registers that latch a 1 when an enabled (unmasked) alarm signal is detected. These registers are read by software to determine which alarm sensor or sensors caused the interrupt. Software clears a bit by writing a 1 to it. The software must either resolve the cause of the alarm or disable the alarm (mask it) for the ISR register bit to be cleared by writing a 1.
