6.2.2.4.6
The real-time clock register is a 32-bit read write register. It contains the current value of the real-time
clock. A write to the RTC resets the seconds timer to zero. This register is locked after reset by default.
Unlocking is accomplished by writing 0x55CC AA33 to its associated key register. See

1
Real-time clock interrupt request. Thee bits determine the interrupt priority level of the RTC.
Refer to
Once per second interrupt. This status bit is set every second. It should be cleared by the
software.
Alarm interrupt. This status bit is set when the value of the RTC equals the value programmed in
the alarm register.
Reserved
Real-time clock source
0 RTC assumes that it is driven by 20 MHz to generate the seconds pulse.
1 RTC assumes that it is driven by 4 MHz
Second interrupt enable. If this bit is set, the RTC generates an interrupt when the SEC bit is set.
Alarm interrupt enable. If this bit is set, the RTC generates an interrupt when the ALR bit is set.
Real-time clock freeze. If this bit is set, the RTC stops while FREEZE is asserted.

0 RTC is disabled
1 RTC is enabled
