Write second byte of coefficient in I

2C address-0X1F

Write third byte of coefficient in I

2C address-0X20

Write fourth byte of coefficient in I

2C address-0X21

Write 1 to W1 bit and write 1/0 to RBS in address-0X32

Write a set of coefficients from RAM:

Write 7-bits of address to I

2C address-0X1D

Write first byte of coefficient A1 in I

2C address-0X1E

Write second byte of coefficient A1 in I

2C address-0X1F

Write third byte of coefficient A1 in I

2C address-0X20

Write fourth byte of coefficient A1 in I

2C address-0X21

Write first byte of coefficient A2 in I

2C address-0X22

Write second byte of coefficient A2 in I

2C address-0X23

Write third byte of coefficient A2 in I

2C address-0X24

Write fourth byte of coefficient A2 in I

2C address-0X25

10. Write first byte of coefficient B1 in I

2C address-0X26

11. Write second byte of coefficient B1 in I

2C address-0X27

12. Write third byte of coefficient B1 in I

2C address-0X28

13. Write fourth byte of coefficient B1 in I

2C address-0X29

14. Write first byte of coefficient B2 in I

2C address-0X2A

15. Write second byte of coefficient B2 in I

2C address-0X2B

16. Write third byte of coefficient B2 in I

2C address-0X2C

17. Write fourth byte of coefficient B2 in I

2C address-0X2D

18. Write first byte of coefficient A0 in I

2C address-0X2E

19. Write second byte of coefficient A0 in I

2C address-0X2F

20. Write third byte of coefficient A0 in I

2C address-0X30

21. Write fourth byte of coefficient A0 in I

2C address-0X31

22. Write 1 to WA bit and write 1/0 to RBS in address-0X32

Note that: the read and write operation on RAM coefficients works only if LRCIN switching on rising edge.

And, before each writing operation, it is necessary to read the address-0X32 to confirm whether RAM is

writable current in first. If the logic of W1 or WA is high, the coefficient writing is prohibited.
