Description
These bits set the functionality of Pin 14:
These two bits define the input threshold for 2-wire fan speed measurements (low frequency mode
only):
Bypass 2.5 V attenuator. When set, the measurement scale for this channel changes from 0 V (0x00) to
2.2965 V (0xFF).
Bypass V
2.2965 V (0xFF).
Bypass 5 V attenuator. When set, the measurement scale for this channel changes from 0 V (0x00) to
2.2965 V (0xFF).
Bypass 12 V attenuator. When set, the measurement scale for this channel changes from 0 V (0x00) to
2.2965 V (0xFF).
