I am using Aduc814 converter in my project. I couldn't generate a clock pulse frequency not more than 46Khz.

The on board frequency is 32 Mhz  and set the PLLCON register to 0 for get the max core freuency as 16.78 Mhz. I tested my code, just i toggle the  pin P3.7 in my main loop. But it couldn't generate the clock pulse more than 46 khz frequency. What could be the problem?


I want to communicate with my I2C enabled sensor has minimum 100khz operating clock frequncy. I am not using the ADuc I2C module.


Kindly help me.
