System Configuration
5.5.5
The RTC programmable register map occupies 32 bytes of memory-mapped space. Reading undefined
portions of the memory map returns all zeros; writing has no effect.
All RTC registers are 32 bits wide that are located on 32-bit address boundaries and should only be
accessed as a 32-bit quantities.
All addresses used in this section are offsets from the RTC base, as defined in
Table 5-33
