XM XM / EXTENDED MODE XM BUS MODE CHANGE CONFIGURATION REGISTER ACCESSES AND BROADCAST / MULTI-CAST TRANSACTIONS TO DEVICES ON A XM BUS

摘要

In embodiments, the device includes an input interface for receiving, from a host computer, a broadcast command including an access mode indication, and a decoding circuit coupled with the interface. The decoding circuitry, based at least in part on the received access mode indication, for a broadcast instruction to access one or more predefined setup or control registers of one or more devices, or to access one or more internal registers of one or more devices. To implement access to setup or control registers, or one or more internal registers, in response to the decision to be sent. In embodiments, the device is disposed on a memory module coupled to the host computer.
