Instructions for Recapturing Analog Channels 0 and 1

Step 1.  Collect the following:

• Two M68EVB912B32 evaluation boards (one for the master and one as the slave)
• BDM cable with 2X3 header connector (included in your HC12 cardboard box)
• A 11.5V source and a 5V source
• A few single header (f-f) connector wires

Step 2.  Configure the boards

• On the Master:
  Set the jumpers W4 = 1 and W3 = 0
• On the Slave (the board to be programmed):
  Set  the jumpers W4 = 0, W3 = 0, W8=11.5V(i.e. Vpp), and W7=Vpp
• For the BDM cable:
  Make the connections such that the Master has BDM out connected to the BDM in on the Slave.
• Power up the two boards and the 11.5V source (could use a prototype board in Digital Lab).

  Step 3. Download the new Debugdlc.s19 file

• Startup a terminal window (appropriately configured)
• Type the following as illustrated below (with a return after each line)
  R> STOP
  S> FBULK
  S> FLOAD
• Then download the Debugdlc.s19 file (send text file using Windows 3.11 terminal using the option for waiting after each line ...)

Step 4. Power down and disconnect 11.5V source and reset W7 to VDD

Step 5. Remove the resistors R7 and R8 and place 2-header pins in their place

Step 6. Wire wrap pin at R7 to PDLC0 and pin at R8 to PDLC1

Step 7. You are finished
