Description
These bits set the functionality of Pin 14.
00 = TACH4 (Default)
01 = THERM
10 = SMBALERT
11 = Reserved
THERM Disable = 0 enables THERM overtemperature output assuming THERM is correctly
configured (0x78, 0x7C, and 0x7D).
THERM Disable = 1 disables THERM overtemperature output on all channels. THERM can
also be disabled on any channel by:
Writing ? 64 ? C to the appropriate THERM temperature limit in Offset 64 mode.
Writing ? 128 ? C to the appropriate THERM temperature limit in twos complement mode.
Max/Full on THERM = 0 indicates that fans go to 100% when THERM temperature limit is
exceeded.
Max/Ful l on THERM = 1 indicates that fans go to maximum speed (0x38, 0x39, 0x3A) when
THERM temperature limit is exceeded.
Bypass +2.5V IN attenuator. When set, the measurement scale for this channel changes from
0 V (0x00) to 2.25 V (0xFF).
Bypass V CCP attenuator. When set, the measurement scale for this channel changes from
0 V (0x00) to 2.25 V (0xFF).
Bypass +5 V IN attenuator. When set, the measurement scale for this channel changes from
0 V (0x00) to 2.25 V (0xFF).
Bypass +12 V IN attenuator. When set, the measurement scale for this channel changes from
0 V (0x00) to 2.25 V (0xFF).
1. This register becomes read-only when the Configuration Register 1 (0x40) Lock bit is set to 1. Any further attempts to write to this register
have no effect.

If GPIO2 is set to input, this register reflects the state of the pin. If GPIO2 is configured as an
output, writing to this register asserts the output high or low depending on the polarity.
If GPIO1 is set to input, this register reflects the state of the pin. If GPIO1 is configured as an
output, writing to this register asserts the output high or low depending on the polarity.
GPIO2 polarity bit. Set to 0 for active low. Set to 1 for active high.
GPIO1 polarity bit. Set to 0 for active low. Set to 1 for active high.
GPIO2 direction bit. Set to 1 for GPIO1 to act as an input, set to 0 for GPIO2 to act as an output.
GPIO1 direction bit. Set to 1 for GPIO1 to act as an input, set to 0 for GPIO1 to act as an output.
