多处理器控制寄存器（MPCR）方法远程处理器可以通过使用多处理器控制暂存器（MPCR，Multiprocessor Control Register）发出远程GO命令来启动本地MVME187双端口RAM中的程序执行。MPCR位于共享RAM位置，与调试器加载它的基地址相距3000美元，它包含用于控制处理器之间通信的两个字之一。MPCR内容组织如下：MPCR状态代码MPCR中存储的状态代码有两种类型：❏ 返回状态（来自187Bug）❏ 总线主控器设置的命令（某些处理器请求的作业）187Bug可能返回的状态代码为：HEX 0（HEX 00）--等待。初始化尚未完成。ASCII R（HEX 52）--就绪。固件监视器正在监视更改。ASCII E（HEX 45）--MPAR指向的代码正在执行。总线主控器可以设置的命令代码是：ASCII G（HEX 47）--使用Go Direct（GD）逻辑***MPAR地址。ASCII B（HEX 42）——使用Go（G）逻辑识别断点。

Multiprocessor Control Register (MPCR) Method A remote processor can initiate program execution in the local MVME187 dual-port RAM by issuing a remote GO command using the Multiprocessor Control Register (MPCR). The MPCR, located at shared RAM location of $3000 offset from the base address the debugger loads it at, contains one of two words used to control communication between processors. The MPCR contents are organized as follows:MPCR Status Codes The status codes stored in the MPCR are of two types: ❏ Status returned (from 187Bug) ❏ Command set by the bus master (job requested by some processor) The status codes that may be returned from 187Bug are:HEX 0 (HEX 00) -- Wait. Initialization not yet complete. ASCII R (HEX 52) -- Ready. The firmware monitor is watching for a change. ASCII E (HEX 45) -- Code pointed to by the MPAR is executing.The command code that may be set by the bus master is:ASCII G (HEX 47) -- Use Go Direct (GD) logic specifying the MPAR address. ASCII B (HEX 42) -- Recognize breakpoints using the Go (G) logic.
