Boot Mode Select - SW10

SW10 is a 4-switch Dip-Switch with three poles in use. This switch selects Boot Mode over Altera
FPGA on the Processor inputs EE0, EE4, EE5 during Power-On reset sequence. Setting SW10/1
(DBG) to ON brings holding EE0 at logic 1 during reset that puts the SC140 core into DEBUG
MODE. In doing so BTM's switch position will be ignored. See
explanation. SW10 is factory set to all ON.
