Hello,

   

I am new to the PSoC environment and working on a project that requires very high precision. I wish to use the more precise 32.768 kHz oscillator on the CY8C424LQQ-BL583 to do the timing for an interrupt. Currently I am using the high frequency clock as an input to the Timer block and it works fine. After enabling the WCO I see no option for changing the source of the clock input (to the Timer), other than HFCLK. I see that the RTC can be used with the WCO clock and could create an interrupt to work but would involve rewriting a lot of the project.

Thanks in advance!
