MVME332XTS
通用可读跳线标头（J22）标头J22提供八条可读跳线。这些跳线可以作为MCchip LCSR（本地控制/状态寄存器）中的寄存器读取（FFF4202D美元）。安装跳线时，位值读取为零，拆下跳线时，位值读取为1。如果安装了MVMEBUG固件，则四条跳线可由用户定义（引脚1-2、3-4、5-6、7-8）。如果未安装MVMEBUG固件，则七条跳线可由用户定义（引脚1-2、3-4、5-6、7-8、11-12、13-14、15-16）。注：引脚9-10（GPIO3）保留用于选择闪存映射（已安装跳线）或EPROM内存映射（已移除跳线）。它们不可由用户定义。MVME出厂时J22设置为全零（所有引脚上的跳线）。J22 15 GPIO7 GPIO6 GPIO5 GPIO1 GPIO4 GPIO3 GPIO2 1 2 GPIO0 16选择的EPROM（工厂配置）用户可定义用户可定义用户可定义参考BUG手册用户可定义IN=闪存；OUT=EPROM参考BUG手册参考BUG手册BUG安装用户可定义用户可定义用户可定义用户可定义IN=闪存；OUT=EPROM用户可定义用户可定义

General-Purpose Readable Jumpers Header (J22) Header J22 provides eight readable jumpers. These jumpers can be read as a register (at $FFF4202D) in the MCchip LCSR (local control/status register). The bit values are read as a zero when the jumper is installed, and as a one when the jumper is removed. If the MVMEBUG firmware is installed, four jumpers are user-definable (pins 1-2, 3-4, 5-6, 7-8). If the MVMEBUG firmware is not installed, seven jumpers are user-definable (pins 1-2, 3-4, 5-6, 7-8, 11-12, 13-14, 15-16). Note Pins 9-10 (GPIO3) are reserved to select either the Flash memory map (jumper installed) or the EPROM memory map (jumper removed). They are not user-definable. The MVME is shipped from the factory with J22 set to all zeros (jumpers on all pins).
