关于GPIO部分描述的疑问

Other Parts Discussed in Thread: C2000WARE

请问在《TMS320x2833x, 2823x System Control and Interrupts Reference Guide》手册中

对GPIO的描述

只描述到了Figure 44中的GPIO64 to GPIO79

为什么没有GPIO80到GPIO87的结构图呢?

 

看了下功能,GPIO80~GPIO87是地址线XA8~XA15,是因为XA0~XA7(对应GPIO40~GPIO47)的结构相同吗?

可是GPIO40~GPIO47(XA0~XA7)隶属GPIOB,有Qualification

GPIO80~GPIO87(XA8~XA15)隶属GPIOC,没有Qualification

 

该怎么理解呢
