Hi, I am using the AFE58JD32, and I am not clear about how to write the coefficient RAM in the section 8.3.10.7.1(the coefficient RAM of the decimation filter coefficients). I did as following step:
1. set SPI_DIG_EN to 0.
2.set COEFF_MEM_ADDR_WR to 0 (reg addr 0x96 = 0x0000).
3. wrote 112 bit to AFE.
but i used the Coefficient Test Mode,it seems the Coefficients are not wrriten to the AFE.
My question is : when I set the COEFF_MEM_ADDR_WR register, i wrote 24bit to AFE by SPI,and then wrote 112bit to AFE, is this right?
could you give me more info about how to set the coefficient RAM? thanks.
