Page 13: Register Map
Register Map The Register Map Page shows the current I C register values (hexadecimal) in the TAS5780M and it can be also used to change the register values. Manually changing register values is accomplished by double- clicking in the desired bit to change. Clicking on Read All Registers allows monitoring of the register status of the amplifier.
Page 14 Three options are available: (1) Dump Current State into a Header file, (2) In-System Debugging and (3) In-System Tuning. Figure 13.

Page 19 Sample Rate Configuration The process flow in the TAS5780M is based on 96 kHz audio signals, but can support multiple sample rates: 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz and 32 kHz. To achieve the rates, It uses its interpolator and two Equalizer banks.
Page 20 This is where the bulk of the frequency compensation occurs. Complex tuning shapes can be made to compensate for deficiencies in speaker response. Figure 21.
