Alarm Operation
The alarm counter is a 24-bit counter in the address
range 04h–06h. When the alarm counter is written, a
seed register is written with the alarm counter value.
When the alarm counter enable (ACE) bit in the Control
Register is set to 1, the counter begins counting down
from the seed value. When the counter reaches zero, it
sets the AF bit in the Status Register, if the AF bit is not
already set. If the AIE and INTCN bits are both set to a
logic 1, the SQW/INT pin goes low and remains low
until AF is written to logic 0. The counter is then
reloaded with the seed value and the countdown
restarts. When the counter is read, the current counter
value is latched into a register, which is output on the
serial data line while the counter continues to decre-
ment. The counter is disabled if the seed value is zero
or if ACE = 0. Whenever the ACE is set from 0 to 1, the
counter is reloaded with the current seed value and the
counter begins to count down. Note: When initializing
or changing the alarm value, the ACE bit should be
enabled after writing the alarm counter bytes.
