code for ISD1760 voice recorder chip

[sam288]

i have made the stand alone mode circuit for !SD1760 as given in datasheet and it works fine..but i tried a lot to control it using SPI mode and it just does not work..for my application i need to record a fixed size message and play the same again...so i was using the set_record and set_play instructions....
.
my sequence of instructions is as follows:
write_cmd(0x01); //power up
write_cmd(0x00);

write_cmd(0x04); //clr_init
write_cmd(0x00);

write_cmd(0x81); //set rec
write_cmd(0x00);
write_cmd(0x10); //start add
write_cmd(0x00);
write_cmd(0x0f0); //end add
write_cmd(0x00);
write_cmd(0x00);

write_cmd(0x04); //clr_init
write_cmd(0x00);

write_cmd(0x80); //set play
write_cmd(0x00);
write_cmd(0x10); //start add
write_cmd(0x00);
write_cmd(0x50); //end add
write_cmd(0x00);
write_cmd(0x00);

write_cmd(0x04); //clr_init
write_cmd(0x00);

what is it that i am doing wrong?? what is the initialization required for the ss,mosi,miso,sclk pins?? can anybody help me please...i am writing code in C...and controller is P89C61.. any help will be extremely valuable to me..
