Function:

0
Default = 00
00 - All settings are taken from user registers
01 - 12 dB of Bass Boost at 100 Hz and 6 dB of Treble Boost at 7 kHz
10 - 8 dB of Bass Boost at 100 Hz and 4 dB of Treble Boost at 7 kHz
11 - 4 dB of Bass Boost at 100 Hz and 2 dB of Treble Boost at 7 kHz
The Tone Control Mode bits determine how the Bass Boost and Treble Boost features are configured.
The user-defined settings from the Bass and Treble Boost Level and Corner Frequency registers are used
when these bits are set to ‘00’. Alternatively, one of three pre-defined settings may be used.
Default = 0
0 - Disabled
1 - Enabled
Function:
The Bass Boost and Treble Boost features are active when this function is enabled.
Default = 0
0 - Disabled
1 - Enabled
Function:
The CS43L43 will limit the maximum signal amplitude to prevent clipping when this function is enabled.
Peak Signal Limiting is performed by first decreasing the Bass and Treble Boost Levels. If the signal is
still clipping, then the digital attenuation is increased. The attack rate is determined by the Limiter Attack
Rate register.
Once the signal has dropped below the clipping level, the attenuation is decreased back to the user se-
lected level and then, the Bass Boost is increased back to the user selected level. The release rate is
determined by the Limiter Release Rate register.
NOTE: The A=B bit should be set to ‘1’ for optimal limiter performance.
