13.2 System Registers
0x00 - Real-Time Clock Register (CLOCK)
This register contains the 32-bit real time clock. It is incremented by the system clock (SYSCLK), which has
been divided by the DIVIDER[6:0] field in the CONFIG0 register. It can be written to any value by each
processor, and can generate an interrupt on the RTC_OVFL status bit in the LP_ISTAT0 register when it
overflows from 0xFFFFFFFF to 0x0.
0x04 - Alarm Register 1 (ALARM1)
This register contains a 32-bit value which is compared against the CLOCK register. When the two registers are
equal, the ALARM1 status bit in the LP_ISTAT0 register is latched and can be enabled to cause an interrupt to
the local processor. To implement a periodic interrupt, add a constant value to this register after each interrupt.
