Bit 13 real-time interrupt 5. The frequency of this interrupt is
shown in Table 11-9 on page 11-12.
RIE4 Real-Time Interrupt Enable Bit 4—This bit enables the
Bit 12 real-time interrupt 4. The frequency of this interrupt is
shown in Table 11-9 on page 11-12.
RIE3 Real-Time Interrupt Enable Bit 3—This bit enables the
Bit 11 real-time interrupt 3. The frequency of this interrupt is
shown in Table 11-9 on page 11-12.
RIE2 Real-Time Interrupt Enable Bit 2—This bit enables the
Bit 10 real-time interrupt 2. The frequency of this interrupt is
shown in Table 11-9 on page 11-12.

Bit 8 real-time interrupt 0. The frequency of this interrupt is
shown in Table 11-9 on page 11-12.
Reserved Reserved
Bits 7–6
HR Hour Flag—This bit enables interrupts occurring at a
Bit 5 one-per-hour rate.
1HZ 1 Hz Flag—This bit enables interrupts occurring at a
Bit 4 1 Hz rate.
DAY Day Interrupt Enable—This bit enables the day inter-
Bit 3 rupt occurring at a midnight rollover (0000 hours) of the
day counter.
