I have questions for the TMS570LS2125's (QFP package) behavior under the pins short condition.
1. #9 pin and #10 pin are shorted.
#9 pin is N.C. externally. In internal, N2HET works as embedded clock and N2HET diagnostic.
#10 pin is VCCIO = 3.3V.
Could you teach me the impact in this case? Is the case no problem?
2. #34 pin and $35 pin are shorted.
#34 pin is the TEST termination with the external pull-down (1kOhm) register.
#35 pin is GIO. This GIO is in input mode and in High condition.
Could you teach me the impact in this case? Is the state transition occurred into internal test mode?
3. #116 pin and #117 pin are shorted.
#116 pin is N_RESET, drive = 4mA.
#117 pin is N_ERROR, drive = 8mA.
In past, I have questioned for same pin short condition in http://e2e.ti.com/support/microcontrollers/hercules/f/312/p/235617/845305.aspx, however additional information is needed in the following conditions.
- #116 pin is in High condition, and #117 pin is in Low condition.
- #116 pin is in Low condition, and #117 pin is in High condition.
Could you teach me the impact in these cases? And, are these pins tied to Low (N_ERROR=Low or N_RESET=Low)?
I'm afraid of the bungle by medium electric potential.
