Abstract
In a multiprocessor environment, by executing cache-inhibited reads or writes to registers, a scan communication is used to rapidly access registers inside and outside a chip originating the command. Cumbersome locking of the memory location may be thus avoided. Setting of busy latches at the outset virtually eliminates the chance of collisions, and status bits are set to inform the requesting core processor that a command is done and free of error, if that is the case.
