i tried and succeed.

i use 16 bits mode in the 9346's hardware pcb design(org pin tried high).

in the sopc, i set the register length to 26, 26=16+6+3+1,

16: word length in the eeprom

6: 9346's address. in 16bit mode, it 's address scope is 0-63;

3: control code;

1: additional bit;

set the clock phase to 0 and clock polarity to 0;

i paste the file *.h and *.c , i hope it will helpful to someone.
