Bits [TACH-DATA15:TACH-DATA0] are the number of clock pulses counted during one fan revolution and
represents the period of the fan revolution (refer to the
Fan Speed Measurement
section). Reading the TACH
data register involves a two-register read. The low byte should be read first. This method causes the high byte to
be frozen until both the high and low byte registers have been read from, preventing erroneous TACH readings.

Bits [TACH-SETTING15:TACH-SETTING0] represent the period of the target fan RPM (in the number of clock
pulses counted during one fan revolution). Refer to the
Fan Speed Measurement
section. Software writes this
register to set the target RPM in the Software-RPM Control mode. When the TACH-MODE bit (bit 1, 0x02) is
cleared ('0'), the TACH setting must be not greater than the value corresponding to the RPM for a 30% duty
cycle. When the TACH mode is equal to '1', the TACH setting must be not greater than the value corresponding
to the allowed minimum RPM at which the fan properly runs.
