18 / 54 page  W83781D/W83781G Publication Release Date: April 14, 2005 - 14 - Revision 2.0 The W83781D/G temperature interrupt has two mode: (1) The first is Interrupt Mode--exceeding TOI causes an interrupt until reset by reading Interrupt Status Register 1 (CR41). Once an interrupt event has occurred over TOI, the interrupt will occur again by the temperature going below THYST. (2) Comparator Mode--setting the THYST limit to 127°C will cause the comparator mode. When temperature exceeds TOI, the interrupt will be generate Interrupt. If the temperature goes below the TOI, the interrupt will be reset. Two interrupt modes are shown as below. TOI THYST *** (1) Interrupt Mode *Interrupt Reset when Interrupt Status Register 1 is read TOI THYST (2) Comparator Mode 127 C IRQ IRQ The temperature sensor 2 or 3 Over-Temperature (OVT) response is same as temperature sensor 1 IRQ signal. TOI THYST *** Over-Temperature Response Diagram *Interrupt Reset when Temperature 2/3 is read OVT# OVT# * (Comparator Mode; default) ((Interrupt Mode) |
