TABLE 41. REGISTER 22H, STATUS REGISTER 3 (POWER-ON DEFAULT 00H)
Bit Name R/W Description
0 FAN0 Status = 0 R 1, if FAN0 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
1 FAN1 Status = 0 R 1, if FAN1 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
2 FAN2 Status = 0 R 1, if FAN2 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
3 FAN3 Status = 0 R 1, if FAN3 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
4 FAN4 Status = 0 R 1, if FAN4 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
5 FAN5 Status = 0 R 1, if FAN5 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
6 FAN6 Status = 0 R 1, if FAN6 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
7 FAN7 Status = 0 R 1, if FAN7 Value is above the High Limit on the previous conversion cycle,
0 otherwise.
TABLE 42. REGISTER 23H STATUS REGISTER 4 POWER-ON DEFAULT 00H
Bit Name R/W Description
0 Int Temp Status = 0 R 1, if Int Value is above the High Limit or below the Low Limit on the
previous conversion cycle, 0 otherwise. This bit is set (once only) if a
THERM
mode is engaged as a result of Int temp readings exceeding the
Int
THERM
limit. This bit is also set (once only) if
THERM
mode is
disengaged as a result of Int temp readings going 5C below Int
THERM
limit.
1 V
BAT
Status = 0 R 1, if V
BAT
Value is above the High Limit or below the Low Limit on the
previous conversion cycle, 0 otherwise.
2 A
IN8
Status = 0 R 1, if A
IN8
Value is above the High Limit or below the Low Limit on the
previous conversion cycle, 0 otherwise.
3 THERM Status = 0 R This bit is set (once only) if a
THERM
mode is engaged as a result of
temperature readings exceeding the
THERM
limits on any channel. This bit
is also set (once only) if
THERM
mode is disengaged as a result of
temperature readings going 5C below
THERM
limits on any channel.
4 AFC Status = 0 R This bit is set (once only) if the fan turns in when in automatic fan speed
control (AFC) mode as a result of a temperature reading exceeding TMIN on
any channel. This bit is also set (once only) if the fan turns off when in
automatic fan speed control mode.
5 Unused R Unused. Will read back 0.
6 CI Status = 0 R This bit latches a Chassis Intrusion event.
7 GPIO16 Status = 0 R When GPIO16 is configured as an input , this bit is set when GPIO16 is
asserted. ("asserted" may be active-high or active-low depending on setting in
GPIO Configuration Register).
R / W When GPIO16 is configured as an output, setting this bit asserts GPIO16.
("asserted" may be active-high or active-low depending on setting in
GPIO Configuration Register).
