cyclone IV asmi read problem

I have a problem in reading EPCS16 with asmi_parallel.

I can write configuration to EPCS with USB blaster, and FPGA configuring and working correctly. But when I try to read my hex data (address 0x70000 in EPCS or ANY other address, e.g. 0, 0x70200 etc) with asmi_parallel I'm getting FFs (all binary 1).

Signaltap shows that asmi module working correctly (see image), but nothing readed.

Device: cyclone IV E EP4CE6F17I7 FBGA-256, EPCS-16 SOIC-8

Quartus: 14.0 build 200 web edition

Code, OSC14 = 14.318 MHz

module bios_asmi(
  input wire OSC14,
  output wire BIOS_DONE,
  //interface to external SRAM where to write readed data
  output reg  RAM_A,
  output reg  RAM_D,
  output reg nWR);
wire  ASMI_DATA;
wire ASMI_BUSY, ASMI_DVALID;
//readed byte counter
reg  CNTR = 17'h0;
always @(posedge OSC14) CNTR <= ASMI_DVALID & ~BIOS_OK ? CNTR+17'h1 : CNTR;
wire PRELAST_BYTE = ~CNTR & (&CNTR); //FFFF
wire LAST_BYTE = CNTR;
//set RDEN on BUSY=0 and counter < done
reg RDEN = 1'b0;
always @(negedge OSC14) RDEN <= (PRELAST_BYTE | LAST_BYTE) ? 1'b0 : ~ASMI_BUSY | RDEN;
//set READ_CMD on RDEN front
reg RDEN_FRONT;
always @(negedge OSC14) RDEN_FRONT <= RDEN;
wire READ_CMD = RDEN & ~RDEN_FRONT;
//read done to other modules
reg BIOS_OK = 1'b0;
always @(posedge OSC14) BIOS_OK <= LAST_BYTE;
assign BIOS_DONE = BIOS_OK;
//latch data to word size register
always @(posedge OSC14) begin
  RAM_D <= ASMI_DVALID & CNTR ? ASMI_DATA : RAM_D;
  RAM_D <= ASMI_DVALID & ~CNTR ? ASMI_DATA : RAM_D;
end
//latch RAM address
always @(posedge OSC14) RAM_A <= ASMI_DVALID & CNTR ? {1'b0,4'hF,CNTR} : RAM_A;
//write RAM signal
always @(posedge OSC14) nWR <= ~(ASMI_DVALID & CNTR);
//asmi instance
parameter bios_read_addr = 24'h70000;
asmi_bios asmi(.clkin(OSC14), .read(READ_CMD), .rden(RDEN), .addr(bios_read_addr), .reset(1'b0), .dataout(ASMI_DATA), .busy(ASMI_BUSY), .data_valid(ASMI_DVALID));
endmodule

All pins set as "regular io". I've tried other options (programming pin, compiler reserved etc) - no change.

Appreciate for help.
