SWITCHES

The MSC8101ADS has the following switches:
4•2•1

Host I/F Setting - SW1

This switch is using for manually set a Host Bus parameters. When Host Configuration is enable
the DIP switch SW1/1-3 will be connected to Data Bus through tri-state buffers and sampled by the
Processor. The SW1 factory set is all ON.

Emulator Enable (EE) - SW2

This switch controls lines EE0-EE7,EED, connected to appropriate pins of the Processor. When
Reset Configuration executed, EEs lines, involved in one, are driven by FPGA. In fact, they are
EE0, EE1, EE4 and EE5 which sampled at the rising edge of PORESET~. After configuration is
done level of all EE-signals is set by the switch SW2/1-7. Their status may be read out via
BCSR3/0-6. SW2 is factory set to all ON.
