Notes

1. Flags Notation: * = Value is a function of the result of the operation, — = Unaffected, X =

Undefined, C = Carry Flag; 0 = Reset to 0, 1 = Set to 1.

2. Whenever a branch occurs, the pipeline is flushed. It takes one extra cycle to flush the pipeline.

After the flush, no bytes are prefetched.
