PRODUCTION DATA
This register page (shown in Table 7-132) consists of the programmable coefficients for the biquad 1 to biquad 6 filters. To optimize the coefficients register transaction time for page 2, page 3, and page 4, the device also supports (by default) auto-incremented pages for the I2C and SPI burst writes and reads. After a transaction of register address 0x7F, the device auto increments to the next page at register 0x08 to transact the next coefficient value. These programmable coefficients are 32-bit, two’s complement numbers. For a successful coefficient register transaction, the host device must write and read all the four bytes starting with the most significant byte (BYT1) for a target coefficient register transaction. While using SPI for a coefficient register read transaction, the device gives out first byte as dummy read byte therefore the host must read five bytes which includes first byte as dummy read byte and the last four bytes corresponds to the coefficient register value starting with the most significant byte (BYT1).
