Hi there,
Can you confirm if there is a pull down resistor on the TEST pin of MSP430F1121A? Our test setup indicates to us that the 'A' version of the F1121 does not have this pull down resistor on it compared to our earlier use of the non-'A' version.
The datasheet shows this TEST pin should be between 25-90Kohms and also states that this pull down is present in "all versions".
We have a 30Kohm resistor pulldown externally on this pin and currently our test station measures this pin as 30Kohms whcih shows no resistance in parallel to this external pull down resistor. When we used the non-A version of this device, the test station measured about 18Kohm (30Kohm external in parallel with ~40Kohm).
Please confirm this as we need to better understand if this is correct or not.
