16.4.5 RTC interrupt control set/clear register
16.4.6 RTC interrupt status register
16.4.7 RTC masked interrupt status register
Table 258. RTC control register (CR - address 0x4005 000C) bit description
RTIMSC is a R/W register and controls the masking of the interrupt generated by the
RTC. Writing sets or clears the mask. Reading this register returns the current value of the
mask on the RTC interrupt.
Table 259. RTC interrupt mask register (ICSC - address 0x4005 0010) bit description
This register is a RO register. Reading this register gives the current raw status value of
the corresponding interrupt prior to masking. A write has no effect.
Table 260. RTC interrupt status register (RIS - address 0x4005 0014) bit description
This register is a RO register. Reading this register gives the current masked status value
of the corresponding interrupt. A write has no effect.

Description
Raw interrupt event flag register. A read returns the state
of the raw interrupt event flag.
Reserved. Read as zero.
Description
Masked interrupt register status. A read returns the
masked interrupt status as controlled by the ICR register.
Reserved. Read as zero.

Description
Interrupt control register. A read returns the current value
of the RTC control register.
Writing 0 masks the interrupt.
Writing 1 enables the interrupt.
Reserved. Read as zero. Do not modify these bits.
Description
Enables the RTC. Once the RTC is enabled through
this bit, any writes to this bit have no effect on the RTC
until a power on reset (POR).
RTC disabled.
RTC enabled.
