8.6.2.1 Programmable Coefficient Registers: Page 2

This register page (shown in GUID-A280D9E6-ED85-48B4-9644-4C923DC38DD2.html#T5453282-93B) 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 four bytes starting with the most significant byte (BYT1) for a target coefficient register transaction. When using SPI for a coefficient register read transaction, the device transmits the first byte as a dummy read byte; therefore, the host must read five bytes, including the first dummy read byte and the last four bytes corresponding to the coefficient register value starting with the most significant byte (BYT1).
