M68EVB908QL4 Startup
Follow these steps to connect and power on the board for the default Monitor operation.
Note: LIN slave communication firmware is installed in the QL4 flash at the factory.
Refer to Motorola application note AN2633/D LIN Drivers for SLIC Module of
MC68HC908QL4 for details. This application note and software example may be found
on the Motorola web site.
1) Inspect the U1 and U2 sockets for proper installation of a QL4 device in one of the sockets.
2) Install the provided Wall-Plug power supply in an available power outlet and connect to the
EVB PWR jack. If the POWER Indicator is not ON, check the following:
PWR_SEL option jumper installed in the 1-2 position.
+5V_EN option jumper installed on both pins.
3) Install MON08 hosting software for applying the DEBUG port on the host PC.
4) Connect the M68EVB908QL4 board DEBUG serial connector to the host PC COM port
with the provided serial cable.
5) Launch the host MON08 software and mass or bulk erase the QL4 flash to unsecure the
device flash. This is required if the QL4 flash is programmed and the security is unknown.
6) Perform a MON08 restart procedure to start a debug session. Follow instructions and
examples provided with the hosting software.
M68EVB908QL4 OPERATION
The M68EVB908QL4 board provides input and output features to assist in application
development. These features may be isolated from the applied HC08 I/O ports by associated
option jumpers. This allows alternate use of the HC08 I/O ports for other application and
connection on the MCU_PORT connector. Caution should be observed so that the HC08 I/O
port pin applied to an on board feature is not also applied to external components by the user.
MEMORY MAP
The EVB board does not provide any expansion memory or memory mapped peripherals.
Refer to the HC08 device user manual for device memory location and type.
