83xx_bootloader.pdf文档中有如下描述，假如我使用SCI通讯方式是否只能使用如下端口，还是可以通过更改bootload中的SCI配置使用其他的SCI端口？

1.1.5 Device Peripheral Usage
The Bootloaders are used with the 56F83xx device configured in MODE 0 (MA = 0).
The Bootloaders use only internal Data RAM from 0x0000 to 0x0FFF and internal Program
RAM for data buffering.
The Bootloaders initialize only the following 56F83xx device peripherals:
? SCI 0 for 56F836x devices
? SCI 0 for 56F835x devices
? SCI 0 for 56F834x devices
? SCI 1 for 56F832x devices
? CAN
? Timer A
? PLL initialization
Each peripheral is set to its default state when loading is complete.

如：文档描述“ SCI 0 for 56F836x devices” 是否可以通过更改bootloader程序将在线更新的通讯端口设为SCI1？

应该是可以的，但要改的可能不只一个地方，要仔细检查才行。
