推荐答案

您正在将值(或设置)到寄存器中.您的处理器有一个带寄存器ROUTELOC0的TIMER0.可能是"CC0LOC_LOC15"

You're ORing in (setting) a value to a register. Your processor has a TIMER0 with a register ROUTELOC0. It likely has a bit that is "CC0LOC_LOC15"

我建议您查看处理器的数据表，以明确了解这是什么意思.

I recommend looking at the data sheet for your processor to figure out what that means specifically.
