MUX set ptr set the MUX pointer to an address <vector number>+MUX set start address:

With the je (jump ==), jge (jump >=), jl (jump <) and jne (jump <>) commands the program flow

21 can be controlled

depending on values in variables:

vector number The MUX pointer is set to <vector number> + address defined by MUX set

start address

21.Only positive jumps (jump down) can be implemented. If jumps in both directions are required, use these

commands in combination with Branch (see page 53)
