小弟第一次使用CPLD，问各位大哥一个问题：
7128S支持I/O口的多电平，我现在要用3.3V和5V，但是不知道那几个引脚与那个VCCIO之间对应?
希望哪位XD帮忙解答一下！

you'd need to refer to the datasheet for this kind of information.
typically, there're something called "io banks". Inside the pad ring, each io banks can have a seperate io voltag. Just search for bank in the respective datasheet.
I have read the datasheet！
but i didn't find the information about the I/O port or banks！
