I2C-COMPATIBLE SERIAL CONTROL INTERFACE
The TAS5705 DAP has an I2C serial control slave interface to receive commands from a system controller. The
serial control interface supports both normal-speed (100-kHz) and high-speed (400-kHz) operations without wait
states. As an added feature, this interface operates even if MCLK is absent.
The serial control interface supports both single-byte and multibyte read and write operations for status registers
and the general control registers associated with the PWM.
The I2C interface supports a special mode which permits I2C write operations to be broken up into multiple
data-write operations that are multiples of 4 data bytes. These are 6-, 10-, 14-, 18-, ... etc., -byte write operations
that are composed of a device address, read/write bit, subaddress, and any multiple of 4 bytes of data. This
permits the system to write large register values incrementally without blocking other I2C transactions.
