peripheral unit address bus 外围单元地址总线
A table or diagram containing the name and address range of each peripheral addressable by the processor within the memory space.
一个在内存空间中的,包含每个外设的名字和可由处理器设置的地址范围的表格或图表。
The address bus is used by the processor to select aspecific memory location or register within a particular peripheral.
地址总线被处理器用来选择在特定外设中的存储器地址或寄存器。
While you're in there, note in passing how the program imports the GPIO base address from xgpio_l.h -- this is dynamically updated by EDK if you shuffle around the base address of the peripheral.
在处理代码时,请注意程序如何从 xgpio_l.h 导入 GPIO 的基地址 —— 如果变动了外部设备的基地址,EDK 会自动更新它。
