Complete the VERILOG sequence generator RO=4; Repeat RCz5"RO Complete the sequence generator that produces the sequence: 4, 20, 100, 500,... The initial value is 4, each following value is multipled by 5. The controller can be done using 9 states. First draw a state graph of the controller, then complete the provided FSM. The reset and first state are already completed. module controller output as ctl tas ctl, output shift_ctl_t shift_ct, output logicr1_ld, ro_ld, output logic ready, input logic next, input clk, reset logic [3:0] step: task ctrllogic rdy, as_ctl_t as, shift_ctl_t sh, logic r1, logic rO): begin ready
