2.2.3 Target Interface Connection Options
There are four ways to connect the JBICS simulator board to your target system:
• Flex cable — low-noise target interface connection
• 20- pin DIP Emulation Cable — low cost flex cable replacement
• 28- pin DIP Emulation Cable — low cost flex cable replacement
• MON08 cable — target interface connection with MCU FLASH

Description
W1
ICS_OSC
or
OSC1
Jumpers W1 and W4 are configured together for the Oscillator
Source.
W1 ON and W4 ON: JBICS MCU and target board clock signals
supplied by the JBICS board oscillator Y1.
W1 ON and W4 OFF: JBICS MCU clock signal supplied by oscillator
Y1 - Target board has its own clock source.
W1 OFF and W4 ON: JBICS MCU clock signal supplied by target
board.
W1 OFF and W4 OFF: JBICS has no clock source.
W4
OSC1
or
TGT_OSC1
W2
Target
System
Power
Jumper: ICS board system power applied to target cable VDD pin.
No Jumper: Allows using a separate power supply for target system.
W3
Reset
Source
Jumper on position 1&2: RST_IN* from target resets on-board ripple
counters and MCU.
Jumper on position 2&3: ICS RST_OUT (from RST*) resets target.
W5
USB Pull-up
Resistor
Jumper: Connects 1.5Kohm pull-up resistor from USB D- data line to
3.3V
No Jumper: 1.5K ohm pull-up is disabled and PTE4/D should only be
used as I/O Port
