MECS UTX1700PTFE伺服元器件，CS-1000中文说明
全局控制和状态寄存器（GCSR）方法远程处理器可以在本地启动程序执行通过发出远程GO命令，MVME187双端口RAM使用VMEchip2全局控制和状态寄存器（GCSR）。
1、远程处理器执行MVME187通用寄存器0和1中的地址（GPCSR0和GPCSR1）。
2.然后，远程处理器设置VMEchip2的位8（SIG0）LM/SIG寄存器。
MECS UTX1700PTFE伺服元器件这导致MVME187安装断点并开始处决结果与MPCR方法相同（具有前一节中描述的状态代码B）。GCSR寄存器在VMEbus短输入/输出空间中访问。每个通用寄存器都有两个字节宽，发生在一个偶数地址。通用寄存器编号0的偏移量为8美元（本地总线）或4美元（VMEbus），从GCSR寄存器开始。当地GCSR的总线基址为$FFF40100。VMEbus基础
GCSR的地址取决于组选择值和在本地控制和状态中编程的板选择值MVME187的寄存器（LCSR）。执行地址为通过读取以下方式：诊断设施187Bug包中包含一整套硬件用于测试和故障排除的诊断MVME187。这些诊断在MVME187Bug调试包用户手册。

Global Control and Status Register (GCSR) Method
A remote processor can initiate program execution in the local
MVME187 dual-port RAM by issuing a remote GO command
using the VMEchip2 Global Control and Status Registers (GCSR).
1. The remote processor places the MVME187 execution
address in general purpose registers 0 and 1 (GPCSR0 and
GPCSR1).
2. The remote processor then sets bit 8 (SIG0) of the VMEchip2
LM/SIG register.
3. This causes the MVME187 to install breakpoints and begin
execution. The result is identical to the MPCR method (with
status code B) described in the previous section.
The GCSR registers are accessed in the VMEbus short I/O space.
Each general purpose register is two bytes wide, occurring at an
even address.
The general purpose register number 0 is at an offset of $8 (local
bus) or $4 (VMEbus) from the start of the GCSR registers. The local
bus base address for the GCSR is $FFF40100. The VMEbus base
address for the GCSR depends on the group select value and the
board select value programmed in the Local Control and Status
Registers (LCSR) of the MVME187. The execution address is
formed by reading the GCSR general purpose registers in the
following manner: Diagnostic Facilities
Included in the 187Bug package is a complete set of hardware
diagnostics intended for testing and troubleshooting of the
MVME187. These diagnostics are completely described in the
MVME187Bug Debugging Package User's Manual.
❏ In order to use the diagnostics, you must switch directories to
the diagnostic directory.
❏ If you are in the debugger directory, you can switch to the
diagnostic directory by entering the debugger command
