5.6.3
(1) Comparator Interrupt Mode
Setting the T
Comparator Interrupt Mode. Temperature exceeds T
and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event has
occurred by exceeding T
again when the next conversion has completed. If an interrupt event has occurred by exceeding T
and not reset, the interrupts will not occur again. The interrupts will continue to occur in this manner
until the temperature goes below T
Setting the T
following are two kinds of interrupt modes, which are selected by Index 4Ch bit5 :
(2) Two-Times Interrupt Mode
Temperature exceeding T
cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register.
Once an interrupt event has occurred by exceeding T
the T
(3) One-Time Interrupt Mode
Temperature exceeding T
an interrupt. Once an interrupt event has occurred by exceeding T
interrupt will not occur again until the temperature exceeding T
