IDT821054A QUAD PROGRAMMABLE PCM CODEC WITH MPI INTERFACE
Note 1: In block 3 of the Coe-RAM, word 5 to word 8 are used for tone coefficients while word 1 to word 4 are used for GIS coefficients. If users do not want to change the GIS coefficient
while writing tone coefficients to the Coe-RAM, they can stop the procedure of consecutive adjacent addressing (after writing data to word 5) by pulling the CS signal to high, or they can
rewrite word 1 to word 4 with the original GIS coefficients.
