Bit 4 - RECD1 - Disables the Resistance Error Correction (REC) for External Diode 1.
Bit 3 - RECD2 - Disables the Resistance Error Correction (REC) for External Diode 2 and External
Diode 3.
Bit 2 - RANGE - Configures the measurement range and data format of the temperature channels.
Bit 1 - DAVG_DIS - Disables the dynamic averaging feature on all temperature channels.
Bit 0 - APDD (EMC1404 only) - Disables the anti-parallel diode operation. Beta Compensation is
disabled on External Diode 2 and 3 regardless of APDD setting. In addition, External Diode 2 Beta
Configuration register will be ignored.
The Conversion Rate Register controls how often the temperature measurement channels are updated
and compared against the limits. This register is fully accessible at either address.
Bits 3-0 - CONV[3:0] - Determines the conversion rate as shown in

‘0’ (default)- REC is enabled for External Diode 1.
‘1’ - REC is disabled for External Diode 1.
‘0’ (default) - REC is enabled for External Diode 2 and External Diode 3.
‘1’ - REC is disabled for External Diode 2 and External Diode 3.
‘0’ (default) - The temperature measurement range is 0°C to +127.875°C and the data format is
binary.
‘1’ -The temperature measurement range is -64°C to +191.875°C and the data format is offset
binary (see
‘0’ (default) - The dynamic averaging feature is enabled. All temperature channels will be converted
with an averaging factor that is based on the conversion rate as shown in
‘1’ - The dynamic averaging feature is disabled. All temperature channels will be converted with a
maximum averaging factor of 1x (equivalent to 11-bit conversion). For higher conversion rates, this
averaging factor will be reduced as shown in
‘0’ (default) - Anti-parallel diode mode is enabled. Two external diodes will be measured on the
DP2 and DN2 pins.
‘1’ - Anti-parallel diode mode is disabled. Only one external diode will be measured on the DP2
and DN2 pins.
