Table 256. RTC match register (MR - address 0x4005 0004) bit description
Table 257. RTC load register (LR - address 0x4005 0008) bit description
This register is a R/W register. Reads return the status of the RTC. Writes enable or
disable the RTC. Once the RTC is enabled, any writes to bit 0 of this register will have no
effect until after a system reset.
