Using a W65c02 Simulator: Copy a range from high-mem to low-mem |
|
|
Overview: A portion of the SBC30 code has been sliced and edited as SBC30_TestCOPY_01.asm to show the Copy a Range of Memory function that is executed by typing "C" or "c" in the terminal.
The user is prompted to enter: - a 4-digit hex DESTINATION address in low-mem - a 4-digit hex value specifying the number of bytes
Tester: Oshonsoft 6502 Simulator IDE v1.41
Setup: Setup your IDE as shown in the top screenshot. Enable the Input Terminal with an I/O port of $5000. Set the "One-Shot IN Value" to "43" for the letter "C". Within the Input Terminal, click "Send Hex Bytes" and enter "38,30,30,31,31,30,30,31,31,33,30,31" without the quotes. The first 4 hex numbers are the SOURCE address $8001, the next 4 are DESTINATION address $1001, and the final four are $1301 which is the number of bytes to copy. Adjust the 3 Memory Editors to show addresses $0000, $8000 and $1000.
App Operation: Using the FlashROM code, here are the keystrokes needed to produce the adjacent lower screenshot: - Press Reset button - Z 2200 00 - C 8000 1000 2300 - D 2200
Breakpoints: 251, 266, 281, 299, 308, 320. Use <CTRL><F6> to get you to the breakpoints, use <F2> at each to get a feel what is occurring, then continue to the next BP using <CTRL><F6>.
