NIOS2 to 8 bit MM slave block data transfer -- Help

Hi,

I Have a 8bit addressed , 8bit width FIR IP module which i want to interface with NIOS2.

My Module is interfaced with

1. MM Slave Interface 2. Interrupt Sender 3. Clk input.

Entity module_fir is

PORT(

avalon_slave_reset:IN STD_LOGIC;

avalon_slave_address:IN STD_LOGIC_VECTOR(7 DOWNTO 0);

avalon_slave_chipselect:IN STD_LOGIC;

avalon_slave_clk:IN STD_LOGIC;

avalon_slave_read:IN STD_LOGIC;

avalon_slave_write:IN STD_LOGIC;

avalon_slave_writedata:IN STD_LOGIC_VECTOR(7 DOWNTO 0);

avalon_slave_readdata:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);

avalon_slave_FIR_Completed:OUT STD_LOGIC

);

end module_fir;

I am using a MM slave interface with Native addressing, which s giving me Address mapped from 0x9000 to 0x93ff to my slave.

the Control Register of the my slave needs to be addressed as 0x0111_1100 to start my processing.

Though i am trying to write the as

IOWR_8DIRECT(FIR_INTERRUPT_0_BASE, 0x1F0, 0x03) ;

to receive the value as below,

if avalon_slave_address = "01111100" then

control_reg_value <= avalon_slave_writedata;

data is not received at the HW end.

PLease help .
