Operating Modes

Note:
all MCUs in the S12 family contain a single-wire background debug
interface which supports in-circuit programming of on-chip non-volatile
memory. This system does not interfere with normal application
resources. It does not use any user memory or locations in the memory
map. The Background Debug Module (BDM) uses a single-wire
communication interface (via the BKGD line) to allow non-intrusive access
to target system memory and registers.
To work in host mode (using the built-in USB to BDM interface):
Make sure that both the “RESET#” and “BKGD” jumpers are inserted.
Make sure that the “POWER SEL” jumper is in the “USB” position.
Connect the host PC to the board through the provided USB cable.
