ADVANCE INFORMATION
The pinstrapping table for PMB_ADDR is shown below. The PMBus address used can be sourced from PMBus register PMBus_ADDR instead of pinstrapping, depending on the state of the bit OVRD_PMB_ADDR in the PIN_DETECT_OVERRIDE register. When pinstrapping is used as the source of PMBus address, the contents of PMBus_ADDR indicating PMBus address (bits [14:8]) are updated with the pinstrapped values.
The table below shows the valid PMBus address configurations for primary and secondary devices through pinstrap.
