12.2.2.6 Raw Interrupt Status Register (RIS)
Reading this register gives the current raw status value of the RTC interrupt prior to mask-
ing. Writing has no effect.
12.2.2.7 Masked Interrupt Status Register (MIS)
Reading the MIS register gives the current masked status value of the RTC interrupt. Writ-
ing has no effect.
