ALERT
Mask
When this bit is a 0, ALERT interrupts are enabled.
When this bit is set to a 1, ALERT interrupts are masked, and the
ALERT pin is always in a high impedance (open) state.
When this bit is a 0, the LM64 is in operational mode, converting,
comparing, and updating the PWM output continuously.
When this bit is a 1, the LM64 enters a low power standby mode.
In STANDBY, continuous conversions are stopped, but a
conversion/comparison cycle may be initiated by writing any value to
register 0x0F. Operation of the PWM output in STANDBY depends on
the setting of bit 5 in this register.
When this bit is a 0, the LM64’s PWM output continues to output the
current fan control signal while in STANDBY.
When this bit is a 1, the PWM output is disabled (as defined by the
PWM polarity bit) while in STANDBY.
These bits are unused and always set to 0.
0: an ALERT will be generated if any Remote Diode conversion result is
above the
Remote High Set Point or below the Remote Low
Setpoint
.
1: an ALERT will be generated only if three consecutive Remote Diode
conversions are above the
Remote High Set Point or below the
Remote Low Setpoint
.

TACHOMETER LIMIT (MSB) and 48
HEX
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.
