Config
The Channel Configuration Register determines which external diode channels are active in the device.
Bit 7 - REM_HOT - Enables circuitry that will remember the last temperature channel that was
determined to be the Hottest and flag an error if the hottest temperature channel changes.
Bit 3 - EXT6_APD - Enables the DP6 / DN7 and DN6 / DP7 pins to support two anti-parallel diode
connections versus a single diode connection.
Bit 2 - EXT4_APD - Enables the DP4 / DN5 and DN4 / DP5 pins to support two anti-parallel diode
connections versus a single diode connection.
Bit 1 - EXT2_APD- Enables the DP2 / DN3 and DN2 / DP3 pins to support two anti-parallel diode
connections versus a single diode connection.
The Filter Configuration Register controls the digital filter on the external diode channels.
Bits 7 - 0 - AVGx_EN- Control the digital averaging that is applied to the External Diode X temperature
measurements.
‘0’ (default) - The HOTTEST status bit will not be asserted if the hottest temperature channel
changes.
‘1’ - If the hottest temperature channel changes, then the HOTTEST status bit will be asserted.
‘0’ (default) - The DP6 / DN7 and DN6 / DP7 pins do not support two anti-parallel diode
connections. The pins will only monitor a single external diode (External Diode 6).
‘1’ - The DP6 / DN7 and DN6 / DP7 pins support two anti-parallel diode connections (External
Diode 6 and External Diode 7).
‘0’ (default) - The DP4 / DN5 and DN4 / DP5 pins do not support two anti-parallel diode
connections. The pins will only monitor a single external diode (External Diode 4).
‘1’ - The DP4 / DN5 and DN4 / DP5 pins support two anti-parallel diode connections (External
Diode 4 and External Diode 5).
‘0’ (default) - The DP2 / DN3 and DN2 / DP3 pins do not support two anti-parallel diode
connections. The pins will only monitor a single external diode (External Diode 2).
‘1’ - The DP2 / DN3 and DN2 / DP3 pins support two anti-parallel diode connections (External
Diode 2 and External Diode 3).
‘0’ (default) - Digital Averaging is disabled.
