如何在不使用big libs的情况下在XC32中读取/写入PIC32MX270F256B上的核心定时器？

好的一天，我想简单地读写核心定时器——32位定时器，它对SysCLK循环进行计数。我不需要中断它，我不需要任何花哨的东西，我只是想用它来测量delta时间。当然，我可以使用外围定时器模块，但这些可以做很多其他事情。S和可以被捆绑或运行在从SysCLK分拆的PBLK中，或者甚至从外部源运行或参与生成PWM或脉冲宽度测量。在SISCLK上（在这MIPS内核中似乎是固有的）具有一个简单的32位自由运行计数器将是非常方便的。我如何用XC32简单地读取核心定时器的当前值，而不必导入任何额外的LIB，如PLIB或配置器或和声？读一个32位寄存器并不难，非常感谢，杰西。

    Good Day,
I'd like to simply read and write the core timer -- the 32 bit timer that counts SYSCLK cycles.
I don't need interrupts off of it, and I don't need anything fancy, I just want to use it to measure delta time.
Sure, I could use the peripheral timer modules but those can do lots of other things and may be tied up or running on a PBCLK that's divided down from SYSCLK or even running from external sources or involved in generating PWM or pulse width measurement.

Having a simple  32bit free running counter on SYSCLK (which seems to be inherent in this MIPS core) would be super handy!

How do I simply read the current value from the core timer with XC32, without having to import any extra libs like plib or configurator or hARMony?

It shouldn't be that difficult to read a 32 bit register someplace.

Thank you very much,

Jesse
