switches:
This switch is used to select the power source for the debugging MCU
board.
When 'EXTERNAL' is selected, an external power supply is the
source for the debugging MCU board.
When 'USER SYSTEM' is selected, the VCC power supply on the
user system is the source for the debugging MCU board.
This jumper is used to select the clock signal for input to the MCU on
the debugging MCU board.
When 'XTAL' is selected, the input clock signal is from the crystal
resonator on the debugging MCU board. When 'USER CLK' is
selected, the input clock signal is from the EXTAL pin on the user
system.
The crystal resonator for supplying the external clock signal is
mounted here when 'XTAL' has been selected on the clock-selection
jumper.
This switch is used to input reset signals manually to the debugging
MCU board.
These switches are used to enable or disable the input of /RES and
NMI signals from the user system and connect or disconnect the user
system.
