EXAMPLE 2
If you have four 8 bit emulators daisy-chained together, a /W32 parameter would cause the loader to
perform a 32 bit split between those units. Bytes 0,4,8.. would be placed in the LAST emulator in the
chain. Bytes 1,5,9.. would land in the next to last emulator. Bytes 2,6,10.. would be end up in the next
emulator. Finally bytes 3,7,11… would be found in the FIRST emulator in the chain. Again the byte
ordering is determined by the emulator daisy-chain order.
EXAMPLE 3
If you are loading into a 16 bit emulator, you must specify a /W16 parameter. 16 bit emulators look like
two daisy-chained 8 bit units to the loader. The /W16 parameter tells the loader to load BOTH bytes. The
EVEN bytes will be placed in the byte connected to D0-D7 on a standard 16 bit EPROM. The ODD bytes
will show up on pins D8-D15. Since the bytes are “daisy-chained” internally, you can not change the byte
ordering. If your target expects the first byte in the file to end up on data bits D8-D15, you will need to run
SWAP.EXE on the file before downloading it. You will find SWAP.EXE in the UTIL sub-directory.
If your system is not running at this point, check the
troubleshooting section for suggestions. If that does not
resolve the problem, PLEASE CONTACT OUR
TECHNICAL SUPPORT PEOPLE at any of the
numbers listed on page 1. We are confident that we can
solve the problem in a timely manner!
Enhancements
Once basic functionality is established, you may choose to speed-up your downloads. The download speed
defaults to its slowest setting to insure compatibility with all printer ports. The self-test program does a
reliability test at each setting. If the reliability test shows that the FAST transfers are reliable, you can use
the /D0 parameter. If the test shows MEDIUM speed transfers are reliable, use the /D1 setting. If only the
SLOW transfers were reliable, leave the parameter off or specify the default /D2.
After you have used the emulator for a while and gained confidence that it is loading reliably, you can add a
/V0 parameter to tell the loader to skip the verify operation. This will reduce your load times by over 50%.
Econo ROM II incorporates a memory retention feature. This allows you to turn the target’s power on and
off without loosing the program loaded into the emulator’s memory. This allows you to test power-up reset
circuits and program behavior. Econo ROM II draws backup power for its SRAMs from the PC’s printer
port. The emulator senses target power and isolates its SRAM from the target power when the target is
turned off. This permits safe target power cycling without the maintenance issues of batteries. The memory
retention feature will work as long as the PC is powered up.
