TACHOMETER LIMIT (LSB) REGISTERS
These registers contain the current 16-bit Tachometer Count, representing
the period of time between tach pulses. Fan RPM = (f
*
5,400,000) /
(Tachometer Count), where f = 1 for 2 pulses/rev fan; f = 2 for 1 pulse/rev
fan; and f = 2/3 for 3 pulses/rev fan. See the Applications Notes section
for more tachometer information. Note that the 16-bit tachometer MSB and
LSB are reversed from the 16 bit temperature readings.
