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.
