I want to read/write eeprom area via BDM mode. Main problem is with connection

I didn't receive any answer from processor. I'm waiting for 150cycles ect ect... but I didn't reiceve any data.


Can you look on attached file, and write me suggestions?


Perhaps is problem with reset time? I don'f find any documentation with detailed explanation of DBM.


Test traget is MC9S12DB128 @ 4MHz clock.

Best regards!
