DATA SHEET REV 0.6
5.18 COEFFICIENT STORAGE PAGES (PAGES 8, 9, 10 and 11)
Addresses 16 to 31 are used to download the 32 user programmable filter coefficients when PAGE is set to
8, 9, 10 and 11. Page 8 is for coefficients 0 through 7, page 9 is for coefficients 8 through 15, page 10 is for
coefficients 16 through 23, and page 11 is for coefficients 24 through 31, where coefficient 0 is the first coefficient
and coefficient 31 is the middle coefficient of the filter’s impulse response. The 16 bit 2’s complement coefficients
are stored in two bytes, least significant byte first, for example, the LSBs of coefficient 0 are stored in address 16
and the MSBs in address 17.
TO LOAD A COEFFICIENT THE USER MUST WRITE THE LSBYTE FIRST FOLLOWED BY THE
MSBYTE. Unknown values will be written into the LSBs if the MSB is written first. The coefficient registers are write
only.
