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. Unlocking is accomplished by writing 0x55CCAA33 to its as-
sociated key register. See
The RTCAL is a 32-bit read/write register. When the value of the RTC is equal to the
value programmed in the alarm register, a maskable interrupt is generated.
The alarm interrupt will be generated as soon as there is a match between the ALARM
field and the corresponding bits in the RTC. The resolution of the alarm is 1 sec. This
register is locked after RESET. Unlocking is accomplished by writing 0x55CCAA33 to
its associated key register. See
nism.

Once per second interrupt. This status bit is set every second. It should be cleared by the soft-
ware.
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.
Real-time clock enable
0 = RTC is disabled
1 = RTC is enabled
