CYCLONE PORT
The Cyclone port is a 16 pin header compatible with a Cyclone development cable. Applying
this cable allows supporting host tools to load and control the QY4 during development. The
MON_EN, JP1 position 1, CLK_EN, and +5V_EN option jumpers should be open when
applying this port.
N/C = No connection
TROUBLESHOOTING
The M68EVB908QL4 is fully tested and operational before shipping. If it fails to function
properly, inspect the board for obvious physical damage first. Verify the setup as described
under GETTING STARTED and START-UP sections of this manual.
1. Verify proper installation of a MC68HC908QL4 in the U1 or U2 socket (not both).
2. Disconnect all external connections to the board except for the serial cable to the PC and
3. Verify the wall plug connections to outlet and the power connector.
4. Verify the power source is enabled and the PWR_EN option is correctly installed.
5. Verify the +5V_EN option is installed and the Power indicator is ON. You should measure
6. Contact
the wall plug. If applying the Cyclone cable, check it’s operation or remove it.
