Jumper
Header
Type Description
W1
Power
source
No jumper installed (factory default) — RKICS board power is disconnected
from the target system. Target circuitry requires an separate supply.
Jumper on pins 1 and 2 — Target power is supplied by the RKICS board. Only
limited power is available for the target. (See 2.3.2.1 RKICS Power Source
Selection Header (W1) (For Target Cable Connection) for more
information.)
W2
Bus
frequency
selection
Jumper on pins 1 and 2 (factory default) — MCU bus frequency is set to
2.4576 MHz (OSC
÷ 4)
and the I/O baud rate is set to 9600.
Jumper on pins 2 and 3 — MCU bus frequency is set to 4.9152 MHz (OSC
÷ 2)
and the I/O baud rate is set to 19,200.
W3
Board
reset
Jumper on pins 1 and 2 (factory default) — The MC68HC908RK2 MCU RESET
signal initiates resets out to the target system.
Jumper on pins 2 and 3 — The target-system RESET signal initiates
resets in to the RKICS on-board MC68HC908RK2 MCU.
W4
W5
Clock
source
W4 W5
1 1
Jumpers installed on W4 and W5 — The RKICS MCU and the
target system OSC1 signals are supplied by the on-board
oscillator at location Y1.
1 0
Jumper installed on W4 and no jumper on W5 — The RKICS
MCU OSC1 signal is supplied by the target system.
0 1
No jumper installed on W4 and a jumper on W5 (factory
default) — The RKICS MCU OSC1 signal is supplied by the
on-board oscillator at location Y1.
0 0
No jumpers installed on jumper headers W4 and W5 —
Connect an external clock source to the RKICS MCU OSC1
input pin via W5 pin 2.
