When enabled the extra temperature data from the TMP468 can be used for either Cell or FET Temperature.
To enable the use of a specific external TMP468 temperature sensor its corresponding bit in Ext TMP Temperature Enable should be set. The TMP468 internal temperature sensor, which even if enabled in the TMP468, is not used within the device . However, if it is enabled it can be read via ManufacturerAccess() 0x0081 TMPRead1( ).
To select a particular external TMP468 temperature sensor for use for CELL or FET temperature then the corresponding selection bit in Ext TMP Temperature Mode should be set.
The DA Configuration [CTEMP1], [CTEMP0] functionality remains the same regardless of the setting of DA Configuration [TMP468_EN].
