MC9S12C32 Supervisor Circuit

[sfb]

Hi,

I want to use MCP100 (450) for microcontroller (MC9S12C32) supervising. But with MCP100 BDM doesn't work. When I remove the MCP100 there is no problem. What is the problem.

Best Regards

Push-pull output of MCP100 is not compatible bidirectional S12 /RESET pin. Supervisor must have open-collector or open-drain output. Also it shouldn't have feature called push button.

C family has LVR feature. LVR makes external supervisor optional.
