A0, A1 = Alarm Mode. Table 6 defines the DS1629 alarm mode, based on the settings of the A0 and A1
bits. These bits define what event will activate the ALRM output. The alarm flagsCAF, TAF, CAL,
TALare functional regardless of the state of these bits. Both locations are read/write and nonvolatile,
and the factory default state disables the ALRM output (A0 = A1 = 0).

OS0, OS1 = Oscillator Output Setting. Table 7 defines the frequency of the OSC output, as defined by
the settings of these bits. Both locations are read/write and nonvolatile, and the factory default state sets
the OSC frequency equal to the crystal frequency (OS0 = OS1 = 1). The output should be disabled if the
user does not intend to use it to reduce power consumption.

CAF = Clock Alarm Flag. This volatile status bit will be set to 1 when the clock comparator is in an
active state. Once set, it will remain 1 until reset by writing to or reading from either the clock register or
clock alarm register. A 0 in this location indicates the clock is not in an alarm condition. This is a read-
only bit (writes to this location constitute a dont care) and the power-up default is the flag cleared (CAF
= 0).
TAF = Thermal Alarm Flag. This volatile status bit will be set to 1 when the thermal comparator is in an
active state. Once set, it will remain 1 until measured temperature falls below the programmed TL setting.
A 0 in this location indicates the thermometer is not in an alarm condition. This is a read-only bit (writes
to this location constitute a dont care) and the power-up default is the flag cleared (TAF = 0).
