I have 2 questions when using MSP430F2619SPM.
1. Schematic as below, R=4.7kΩ，C=10uF, the TEM2 signal is directly to MSP430 ADC, I want to check, if the ext. R/C Value is right? what is the R/C value range?
2. when MSP430F2619SPM using in -55℃，3 Channel ADC of the 6 Channel can not work accurately, while the other 3 channel work normally, but they can work normally after work for a while(suppose the temperature rose after working for some time, and ADC can work normally?)
Does this mean the chip MSP430F2619SPM cannot work continually at -55℃？any Margin for this -55℃?
