Real-Time-Clock APB interface Clock Enable
This bit is used to control the RTC APB clock only, The RTC engine clock source is
from the external 32.768 kHz crystal.
1 = Enable RTC Clock
0 = Disable RTC Clock
Watchdog Timer Clock Enable (write-protection bit)
This bit is the protected bit. It means programming this needs to write “59h”, “16h”,
“88h” to address 0x5000_0100 to disable register protection. Reference the register
REGWRPROT at address GCR_BA+0x100.
The bit default value is set by flash controller. User configuration register congig0
