Description
When this bit is set, Fan 1 smoothing times are multiplied x4 for Remote 1 temperature channel
(as defined in Register 0x62).
When this bit is set, Fan 2 smoothing times are multiplied x4 for local temperature channel
(as defined in Register 0x63).
When this bit is set, Fan 3 smoothing times are multiplied x4 for Remote 2 temperature channel
(as defined in Register 0x63).
When this bit is set, THERM is enabled in manual mode. (Note 1)
Reserved. Do not write to these bits.
V CCP LO = 1. When the power is supplied from 3.3 V STANDBY and the core voltage (V CCP )
drops below its V CCP low limit value (Register 0x46), the following occurs:
Bit 1 in Interrupt Status Register 1 is set.
SMBALER T is generated, if enabled.
PROCHOT monitoring is disabled.
Everything is re-enabled once V CCP increases above the V CCP low limit.
When V CCP increases above the low limit:
PROCHOT monitoring is enabled.
Fans return to their programmed state after a spin-up cycle.

When this bit is set, all fan smoothing times are increased by a further 39.2%.
1. A THERM event always overrides any fan setting (even when fans are disabled).
2. This register becomes read-only when the Configuration Register 1 Lock bit is set to 1. Any subsequent attempts to write to this register fail.

1. If the extended resolution bits of these readings are also read, the extended resolution registers (Reg. 0x76, Reg. 0x77) must be read first.
Once the extended resolution registers are read, the associated MSB reading registers are frozen until read. Both the extended resolution
registers and the MSB registers are frozen.
2. V CC (Pin 3) is the supply voltage for the ADT7475.

1. These temperature readings can be in twos complement or Offset 64 format; this interpretation is determined by Bit 0 of Configuration
Register 5 (0x7C).
2. If the extended resolution bits of these readings are also read, the extended resolution registers (0x76 and 0x77) must be read first. Once
the extended resolution registers are read, all associated MSB reading registers are frozen until read. Both the extended resolution registers
and the MSB registers are frozen.
3. In twos complement mode, a temperature reading of ? 128 ° C (0x80) indicates a diode fault (open or short) on that channel.
4. In Offset 64 mode, a temperature reading of ? 64 ° C (0x00) indicates a diode fault (open or short) on that channel.
