SLIMBUS INTERFACE CONTROL

The WM5102 features a MIPI-compliant SLIMbus interface, providing 8 channels of audio input and 8

channels of audio output. Mixed audio sample rates are supported on the SLIMbus interface. The

SLIMbus interface also supports read/write access to the WM5102 control registers.

The SLIMbus interface on WM5102 comprises a Generic Device, Framer Device, and Interface

Device. A maximum of 16 Ports can be configured, providing up to 8 input (RX) channels and up to 8

output (TX) channels.

The audio paths associated with the SLIMbus interface are described in the “Digital Core” section.

The SLIMbus interface supports read/write access to the WM5102 control registers, as described later

in this section.

The SLIMbus clocking rate and channel allocations are controlled by the Manager Device. The

Message Channel and Data Channel bandwidth may be dynamically adjusted according to the

application requirements. Note that the Manager Device functions are not implemented on the

WM5102, and these bandwidth allocation requirements are outside the scope of this datasheet.

SLIMBUS DEVICE PARAMETERS

The SLIMbus interface on the WM5102 comprises three Devices. The Enumeration Address of each

Device within the SLIMbus interface is derived from the parameters noted in Table 47.
