Description
When this bit is set, fan smoothing times are multiplied x4 for Remote 1 temperature channel
(as defined in Register 0x62).
When this bit is set, fan smoothing times are multiplied x4 for local temperature channel
(as defined in Register 0x63).
When this bit is set, fan smoothing times are multiplied x4 for Remote 2 temperature channel
(as defined in Register 0x63).

V CCP Low = 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:
Status Bit 1 in 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. This register becomes read-only when the Configuration Register 1 (0x40) Lock bit is set to 1. Any subsequent attempts to write to this
register fail.
