TMS570LS3137中大小端的疑问

Other Parts Discussed in Thread: TMS570LS3137

在TMS570LS3137的计数参考手册的1.3章节中描述到“”“The TMS570 family is based on the ARM® Cortex®-R4F core. ARM has designed this core to be used in
big-endian and little-endian systems. For the TI TMS570 family, the endianness has been configured to BE32..”，即字不变的大端格式；但是在cortex-r4的技术参考手册的3.3.1章节中描述到

The processor can treat words of data in memory as being stored in either:
• Byte-invariant big-endian format
• Little-endian format.

即cortex-r4如果运行在大端模式下，支持BE8格式的大端格式。

那么我的理解是：在TMS570LS3137中CPU是运行在大端模式下，即BE8！  对于地址空间例如寄存器的访问是以BE32的格式访问！

以1.3章节中的示例举例，进行字节访问0x0xFFF7F448，应该读写访问的是C2TDELAY[7:0]域。

请问以上我的理解和举例是否正确
