2.2 function description 

2.2.1 System Bus 

 

System Bus includes PXA255 address bus, data bus, memory control 

signals and GPIOs. 
 

System Bus enters CSB by X1. In order to make sure that system bus 

signals have perfect electrical waves, System Bus signals are driven by buffers 
to enhance signals performance.

The buffers signals direction control is control by CPLD on SOM-A255x 

module.
