Notation:
BGE rel
Description:
If the negative flag N is cleared (N = 0, non-negative), place the branch address PC + rel
(relative of the first byte after the Branch instruction) in the program counter PC and clear
the cache-mode flag M; all condition flags remain unchanged. Then instruction execution
proceeds at the branch address placed in the PC
When the branch condition is not met, the M flag and the condition flags remain
unchanged and instruction execution proceeds sequentially.
Note: rel is signed to allow forward or backward branches.
Operation:
If N = 0 then
PC := PC + rel
M := 0
Exceptions:
None.
