Sample Command Sequence
Table 9
Example: The bus master configures the DS1629 in the power-up one-shot mode. It sets the ALRM
output active low with only the thermometer generating an ALRM and disables the oscillator output. It
then sets the clock to 11:30AM on Thursday, January 1, 1998. It sets the thermostat with TH=50°C.
