Power-On Conﬁguration Summary

On the rising edge of PWRGOOD, the CL-PD67XX latches the conﬁguration pin SPKR_OUT*/C_SEL to

determine which sockets are addressed by this device. A ‘1’ on the SPKR_OUT*/C_SEL pin will cause

the device to address Socket 0 (and Socket 1 for the CL-PD6722). A ‘0’ on this pin will cause the device

to address Socket 2 (and Socket 3 for the CL-PD6722).
