45 16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
46 an analog output and a PWM output along with limit, alarm and mask bits for
50 sensor inputs and one internal sensor. Each sensor has a high and low
51 limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
52 generated. The interrupts can be masked. In addition, there are over-temp
53 limits for each sensor. If this limit is exceeded, the #THERM output will
54 be asserted. The current temperature and limits have a resolution of 1
58 in counts of a 22.5kHz internal clock. Each fan has a high limit which
59 corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
66 crossed a programmable minimum or maximum limit. Note that minimum in this
