I need a list of the instructions with the number of cylces needed to compute that instruction. I couln't find that on the web.

We use: st72321

Where can I get this list?

In Visual Debug/Develop goto Help/Help On Instruction menu item.

Each instruction is given a number of cycles required.

This information is also calculated in the simulator, View/ST7 Register have a look at the Time and Instruction counter tabs.

Pls download ''ST7 Family Programming Manual'' from the same site.

It explains all instructions and addressing modes etc.

Hi Bastian,

you can take the PDF-file of the

http://mcu.st.com/files/mcu/4020.pdf

There you find a complete description of each ST7 instruction beginning on page 33, including the number of cycles -cy-.
