Two timers and a fade
The following code demonstrates the difference between the two timers on HCS08 and their respective channels. LED1 is on Timer1 Channel1 and LED3 is on Timer2 Channel0. Their interrupt functions are identical, but their behavior is different due to their respective timers and duties. Pressing SWITCH1 will increase pulseMod and thus decrease the blink rate, whereas pressing SWITCH2 will decrease pulseMod and increase the blink rate. Lastly, LED5 is a good example of exercising the duty cycle. It's duty is being decremented/incremented through the main loop and will thus decrease/increase the duty (time of period) that the led is on.

Freescale HCS908
The onboard demos work as described in the "Getting Started with the M68DEMO908GB60 rev 02)", but the file M68DEMO908GB60demo.mcp does not exist, there is not a "M68DEMS.zip" file included on the demo board CD. UPDATE: M68DEMS.zip is included on the CD underneath the Code Warrior package. But, even still, the code did not contain what was referenced.
Referencing the AN2616_Getting_Started_With_HCS08_and_CodeWarrior references (p4)AN2616SW.zip, which also does not exist with the bundled software. Sheesh.
So the HCS908 is debuggable, out of box, using the db9 serial connector with SCI1.
New project creation:
By selecting "P&E Full Chip Simulation", "P&E Hardware Debugging" and "Motorola Serial Monitor", it will be possible to use either simulation, the serial monitor within the HCS08 FLASH, or BDM to debug code.There is no code overhead as a result of choosing multiple connection methods.
To enable serial monitor connection press switch 4 and switch the power on, set the target to be "Monitor". Once the debugger appears a couple modal dialogs should quickly appear and disappear showing that the FLASH is being erased. If this doesn't happen then there is likely a communications problem and the simulator will then run the program.
Here's the first go at LED manipulation:

Nullable fields in a unique constraint, BAD
Can't have a unique constraint with a nullable field and treat that nullable as a "unique" value.
(Oracle) http://www.adp-gmbh.ch/ora/misc/integrity_constraints.html ,
http://www.techonthenet.com/oracle/unique.php
(Postgresql)http://www.postgresql.org/docs/8.1/interactive/indexes-unique.html
(MySQL5) http://dev.mysql.com/doc/refman/5.0/en/create-table.html
A UNIQUE index is one in which all values in the index must be distinct. An error occurs if you try to add a new row with a key that matches an existing row. The exception to this is that if a column in the index is allowed to contain NULL values, it can contain multiple NULL values. This exception does not apply to BDB tables, for which an indexed column allows only a single NULL.
