pic16f1825振荡器该如何设置

大家好，我是非常新的论坛，这是我的第一篇文章。也有新的PIC16F1825。我选择了PIC，因为我需要做一些非常敏感的输出驱动的下游设备。我试图建立设备使用32兆赫内部振荡器，并AM读取时钟输出上的CKLUOD引脚（RA4）。但是，尽我所能，我只能得到8MHz（如在我的范围内阅读）。我将我的示例代码附加在这里，它只是试图设置设备，然后上下切换一个位（RC0）。我的计划是使用程序集来对时间敏感的例程进行编码，然后转到C编译器来编写UART代码、启用引导加载程序等等。但是我仍然坚持配置。如果你能给我们任何帮助，我们将不胜感激。code snippet here:__CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_OFF & _PWRTE_OFF & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOREN_ON & _CLKOUTEN_ON & _IESO_OFF & _FCMEN_OFF __CONFIG _CONFIG2, _WRT_OFF & _PLLEN_ON & _STVREN_ON & _BORV_HI & _LVP_ON org 0Start 关闭恼人的编译器消息检查你在哪一个银行-我答应检查；错误级别- 302；设置内部振荡器到最高可能的速度；班克斯OsCon；选择银行OSCCon寄存器是在MOVLW 0X70 MOVWF OSCCon MOVLW 0X00 MOVWF OSCTUNY；设置RA4到输出系统时钟（假设这不是隐式的）；BANCSEL PARTA PoCala LATA CLRF LATA BANSEL ANSELLA CLSRF ANSELA BANSEL TrISA CRRF TrISA；设置参考时钟模块；BANSEL CKRCON；MOVLW 0XC0；MOVWF CKRCON；数字输出的RC0和RC1；BANCEL PORTC CRRF PORTC；初始化端口c银行LATC clrf LATC；数据锁存端口c银行ANSELC clrf ANSELC；设置为数字I/O银行TRISC clrf TRISC；设置所有引脚为输出；创建简单的循环以将RC0移动到高处然后移动到低处以读取范围；循环银行PORTC movlw 0x01movwf PORTC；将RC0设置为逻辑1movlW0x00 MOVWF PORTC；设置RCO到逻辑0 Goto BooLoad，我也尝试上传屏幕截图，但没有许可。谢谢各位！

    Hello,
I am very new to the forum, this is my first post. Also new to the PIC16F1825. I chose the PIC because I need to do some very time-sensitive output driving of a downstream device. I am trying to set up the device to use the 32Mhz internal oscillator, and am reading the clock output on the CKLOUT pin (RA4). But, try as I might, I can only get to 8Mhz (as read on my scope). I'm attaching my sample code here, which just tries to setup the device and then toggle a bit (RC0) up and down. My plan would be to use assembly to code the time sensitive routines, then move up to the C compiler to write the UART code, enable the bootloader, etc. But I'm stuck on the configuration. Any help you folks could give would be much appreciated. code snippet here:

__CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_OFF & _PWRTE_OFF & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOREN_ON & _CLKOUTEN_ON & _IESO_OFF & _FCMEN_OFF
__CONFIG _CONFIG2, _WRT_OFF & _PLLEN_ON & _STVREN_ON & _BORV_HI & _LVP_ON
