Note: all MCUs in the S08 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 (also known as Background Debug
Controller, BDC) 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 the board is powered on;
Make sure that the “RESET ENABLE” and “BKGD ENABLE” jumpers in the “USB TO
BDM INTERFACE” section are inserted;
Connect the host PC to the board through the provided USB cable.
