CRD4525-Q1
The on-board firmware can be upgraded by downloading and running the most recent version of the Cirrus
Logic FlexGUI application. If necessary, this application (downloadable at www.cirrus.com/msasoftware)
will automatically upgrade the firmware for an attached CRD4525-Q1 upon start-up.

External Power Stage Interface
A keyed connector (J4) is included to interface with the CRD4412A. The CRD4525-Q1 can be used with or
without a CRD4412A attached.
Without the CRD4412A attached, the CRD4525-Q1 configures itself for 2-channel stereo full-bridge opera-
tion. When the CRD4412A is attached, the CS4525 enables its bass manager and routes the LFE channel
to the CRD4412A which amplifies the signal in mono parallel full-bridge mode. Together, the CRD4525-Q1
and CRD4412A implement a 2.1 configuration.
The CRD4412A must be inserted and removed while power is not applied to the CRD4525-Q1.
