Write a single coefficient from RAM:

Write 7-bis of address to I2C address-0X1D

Write top 8-bits of coefficient in I2C address-0X1E

Write middle 8-bits of coefficient in I2C address-0X1F

Write bottom 8-bits of coefficient in I2C address-0X20

Write 1 to W1 bit and write 1/0 to RBS in address-0X2D

Write a set of coefficients from RAM:

Write 7-bits of address to I2C address-0X1D

Write top 8-bits of coefficient A1 in I2C address-0X1E

Write middle 8-bits of coefficient A1 in I2C address-0X1F

Write bottom 8-bits of coefficient A1 in I2C address-0X20

Write top 8-bits of coefficient A2 in I2C address-0X21

Write middle 8-bits of coefficient A2 in I2C address-0X22

Write bottom 8-bits of coefficient A2 in I2C address-0X23

Write top 8-bits of coefficient B1 in I2C address-0X24

Write middle 8-bits of coefficient B1 in I2C address-0X25

10. Write bottom 8-bits of coefficient B1 in I2C address-0X26

11. Write top 8-bits of coefficient B2 in I2C address-0X27

12. Write middle 8-bits of coefficient B2 in I2C address-0X28

13. Write bottom 8-bits of coefficient B2 in I2C address-0X29

14. Write top 8-bits of coefficient A0 in I2C address-0X2A

15. Write middle 8-bits of coefficient A0 in I2C address-0X2B

16. Write bottom 8-bits of coefficient A0 in I2C address-0X2C

17. Write 1 to WA bit and write 1/0 to RBS in address-0X2D

Note that: the read and write operation on RAM coefficients works only if LRCIN (pin-15) switching on rising

edge. And, before each writing operation, it is necessary to read the address-0X24 to confirm whether RAM

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