PROM Programming Examples
When you start the SHIFT-LOAD 3 function, you are prompted for a baud rate.
You can select any standard baud rate from 110 to 9600. In this example, 9600
baud is entered. You are then prompted for a starting address in the file to be
down-loaded. This file starting address is loaded into location 00H in the RAM
buffer. In this case, a file starting address of 380H is selected. After you enter the
starting address, the message "HEX LOAD MODE" is displayed. You can now
initiate the down-load from the host system.
When using an Intel development system, enter ISIS commands to tell the devel
opment system to down-load the file to the teletype port as follows:
>SPEED 9600
> C O P Y :F1 :CODE4.IUP TO :TO:
>COPIED :F1 :CODE4.IUP TO :TO:
>
After the file is read, the message "END OF FILE" is displayed on the iUP-201 A
alphanumeric display. Press the < CLEAR > key to return to the IUP READY
prompt. If the file is not in Intel 8080 hexadecimal format, the message "ILLE
GAL FILE TYPE" is displayed.
In this example, the file is loaded into the RAM buffer, with address 380H of the
file stored at address 00H of the RAM buffer (see Figure 4-1).
