RIT Interrupt in Keil uVision

dameash

Hello,

I want to use RIT interrupt to generate a interrupt after a specific time period. I am using keil uVision 4 on lpc1768 device.

I have the code that is compiled without any errors. But when ever i try to debug the code, i donot see the RITCOUNTER value to increase and RIT interrupt never generated because of which the ISR routine is never reached. Can anyone help me to figure out what i am doing wrong.

 

Thank you

Asha

    Hello,
    According to the user manual www.nxp.com/.../UM10360.pdf

    i have made sure that i have a value for the RICOMPVAL register, set the bit in the RICTRL register. I have also enabled the NVIC register for the RIT interrupt. When i am using the debug session, these registers to get the necessary value. Only the RICOUNTER doesnt increase with clock cycles as mentioned in the manual. This is where i am not sure what i am doing wrong. Please help.
