Alarm Registers
The alarm registers for the real-time clock, interval timer, and cycle counter all operate in the same
manner. When the value of a given counter equals the value in its associated alarm register, the
appropriate flag bit is set in the status register. If the corresponding interrupt enable bit(s) in the status
register is set, an interrupt is generated. If a counter and its associated alarm register are write protected
when an alarm occurs, access to the device becomes limited. (See “Status/Control”, “Interrupts”, and the
“Programmable Expiration” sections.)
STATUS/CONTROL REGISTERS
The status and control registers are the first two bytes of page 16 (see “Memory Map”, Figure 4).

Cycle counter alarm flag
When a given alarm occurs, the corresponding alarm flag is set to a logic 1. The alarm flag(s) is cleared
by reading the status register.

its corresponding alarm flag is set (see “Interrupts” section).
