FUNCTION
D15
TSCAN
0
R/W
TEMP Configuration when AutoTemperature is selected
0 => TEMP1 is used for autotemperature function
1 => TEMP2 is used for autotemperature function
D15
A1CONF
0
R/W
AUX1 Configuration.
0 => AUX1 is used for voltage measurement.
1 => AUX1 is used for resistance measurement.
D14
A2CONF
0
R/W
AUX2 Configuration.
0 => AUX2 is used for voltage measurement.
1 => AUX2 is used for resistance measurement.
D12
ATEMES
0
R/W
Auto Temperature (TEMP1 or TEMP2) measurement enable
0 => Auto temperature measurement is disabled.
1 => Auto temperature measurement is enabled.
TEMP1 or TEMP2 selection is depends on TSCAN bit.
D11
AA1MES
0
R/W
Auto AUX1 measurement enable
0 => Auto AUX1 measurement is disabled.
1 => Auto AUX1 measurement is enabled.
D10
AA2MES
0
R/W
Auto AUX2 measurement enable
0 => Auto AUX2 measurement is disabled.
1 => Auto AUX2 measurement is enabled.
D9
IGPIO1
0
R/W
Enable GPIO1 for Auto/NonAutoScan interrupt (this programmability is valid only if D11 & D9
of control register 23H/page 2 are 0’s)
0 => GPIO1 is not selected for interrupt.
1 => GPIO1 is used to send an interrupt. Interrupt is generated when any of TEMP (TEMP1 or
TEMP2), AUX1 or AUX2 are not passing threshold
D8
THMXFL
0
R
Max threshold flag for Temperature (TEMP1 or TEMP2) measurement.
0 => Temperature measurement is less than max threshold setting.
1 => Temperature measurement is greater than or equal to max threshold setting.
D7
THMNFL
0
R
Min threshold flag for Temperature (TEMP1 or TEMP2) measurement.
0 => Temperature measurement is greater than min threshold setting.
1 => Temperature measurement is less than or equal to max threshold setting.
D6
A1HMXFL
0
R
Max threshold flag for AUX1measurement.
0 => AUX1 measurement is less than max threshold setting.
1 => AUX1 measurement is greater than or equal to max threshold setting.
D5
A1HMNFL
0
R
Min threshold flag for AUX1 measurement.
0 => AUX1 measurement is greater than min threshold setting.
1 => AUX1 measurement is less than or equal to max threshold setting.
D4
A2HMXFL
0
R
Max threshold flag for AUX2measurement.
0 => AUX2 measurement is less than max threshold setting.
