CS4525

When the LimitAll feature is activated, attenuation will be applied to all channels when a single channel

exceeds the maximum threshold and released when the level of all channels is below the minimum

threshold. When the LimitAll feature is de-activated, limiter attenuation will be applied and released on a

per-channel basis and will only affect the channel on which the limiter event occurred.

The limiter can be enabled by setting the EnLimiter bit in the Limiter Cfg 1 register

The limiter can also be used in conjunction with the thermal limiter function to provide thermal error pro-

tection to the CS4525. The thermal limiter function is described in Thermal Limiter on page 39.
