I am trying to read the registers on a locked/secured 9s12 and i get this "No BDM Tx routine was found" as an error.

I am using USBDM_ReadMemory(). The error is there but some data are returned. So for example if i try to read the Part ID, address 0x001A, i get 0x0022 as a result.

I am expecting to get something like 0x4220. Do i need to pull moda and modb to gnd?
