TBDML BDM_IN and BDM_DRV

[DanielO]

Hi, I have a question about the schematic for the TBDML.. I am wondering why BDM_IN and BDM_DRV are connected to 2 pins on the micro. From what I can see in the code BDM_IN needs to only be connected to PTA6, however the BDM_DRV (BDM_DIR1/2 in the code) pins are both used. I don't understand why it's necessary though.. Thanks.

Hi,

BDM_IN is needed on both PTA6 (Rx routines) and the timer input PTE1 (SYNC pulse measurement).

BDM_DRV is also needed on 2 pins. One in port A for faster Rx routines and one on another port for faster Tx routines.

Sorry, but I need all these connections in my software. You would need to change it if you want to eliminate the double connections.
