2.4 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).
