Note 1. Threshold violations do not generate alarm interrupts until the Interrupt Enable (IE) bit is set.
Note 2. PIO Interrupts are cleared by resetting the PIO bit in the Special Feature Register.
Note 3. SUSPEND state shown in this timing diagram refers to the DS2756 cycling between Active
and Suspend mode at a rate determined by the PIE bit settings. Suspend state is entered by
setting PIE bits to a non-zero value, setting PMOD=1, and then driving DQ low for longer
than 2s.
Note 4. Interrupts on PIO not reset by software are automatically cleared when entering suspend
mode.
Note 5. Alarm threshold violations do not generate interrupts if Suspend mode is enabled
(PIE ≠ 00b).
