8.6.4.2 Programmable Coefficient Registers: Page 3

This register page (shown in Table 8-112) consists of the programmable coefficients for the biquad 7 to biquad 12 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 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.
