Message:

(bobd) now configures temp alarms to stay on while out of range (via686a default is to clear alarm when reg is read)

+// The following register sets temp interrupt mode (bits 1-0 for temp1, 
+// 3-2 for temp2, 5-4 for temp3).  Modes are:
+//    00 interrupt stays as long as value is out-of-range
+//    01 interrupt is cleared once register is read (default)
+//    10 comparator mode- like 00, but ignores hysteresis
