PCLK怎么用

大家好，
用于P-端口的SAMTEC扩展连接器的引脚44是PGPIO（16），用作GPIF II接口的默认同步时钟。我能够测量和确认这个输出，同时修改“SLaveFioAsiNC”示例（调整到100 MHz输出），代码如下：
包括“CYU3PIB.H”
/--------------------------
CYU3PPIBCCROXYT PIBCHILL；CYU3PRESTROSTATUS SUT APIRATSTAtiON CYU-U3PY成功；/*初始化P-端口块。* / pibclock.clkdiv = 4；pibclock.clksrc = cy_u3p_sys_clk；pibclock.ishalfdiv = cyfalse；/*禁用DLL同步GPIF * / pibclock.isdllenable = cyfalse；apiretstatus = cyu3ppibinit（cytrue，&；pibclock）；
我现在的工作在GPIO的操作和已使用“gpioapp”的例子为出发点。但是我不能够得到PCLK时钟输出信号我开始之前…它根本没有输出任何东西。我注意到，“gpioapp”示例使用“gpioclock”和所谓的“cyu3pgpioinit API。这些配置有什么干扰吗？

  Hi everyone,
     
    Pin 44 of the Samtec expansion connector for the P-port is p_gpio[16] and used as the default synchronous clock for the GPIF II interface.  I was able to measure and confirm this output while modifying the "SlaveFifoAsync" example (adjusted to a 100 MHz output) with the following part of code:
     
    #include "cyu3pib.h"
    //---------------------------
     
    CyU3PPibClock_t pibClock;
CyU3PReturnStatus_t apiRetStatus = CY_U3P_SUCCESS;

/* Initialize the p-port block. */
pibClock.clkDiv = 4;
pibClock.clkSrc = CY_U3P_SYS_CLK;
pibClock.isHalfDiv = CyFalse;
/* Disable DLL for sync GPIF */
pibClock.isDllEnable = CyFalse;
apiRetStatus = CyU3PPibInit(CyTrue, &pibClock);
     
     
    I am now  working on GPIO manipulation and have been using the "GpioApp" example as a starting point.  However I am not able to get the PCLK to output the same signal I was getting before... it isn't outputting anything at all.  I noticed that the "GpioApp" example uses a "gpioClock" and calls the "CyU3PGpioInit" API.  Are these configurations somehow interfering with eachother?
