Notes
1. After an external pin reset, the Watchdog Timer Control register is reset to 00h. After a Watchdog Timer time-out
2. When the CPU reads this register, the current sampled value of the port is read.
3. Read-only if RTC is locked; Read/Write if RTC is unlocked.
4. After an external pin reset or a WDT reset, the RTC Control register is reset to x0xxxx00b. After an RTC Alarm
reset, the Watchdog Timer Control register is reset to 20h.
Sleep-Mode Recovery reset, the RTC Control register is reset to x0xxxx10b.
