CCS/MSP430FR5857: UNABLE TO GENERATE INTERRUPT

Part Number: MSP430FR5857

Tool/software: Code Composer Studio

Hello Sir

I am using MSP430FR5857 MCU . I am Using Texas Driver Library . I have tried to generate interrupt using timer TA1 using CCR1 but its not generating properly mean to say its generating at definite time which is not matching with compare value. i have tried to generate interrupt at every 1ms but its generating at 0.014 ms . Please reply i stuck into it.

Thanks and Regards

Hello,

Which clock source have you selected for your timer?
Can you maybe share your code?

i have tried using both smclk and aclk as clock source and where SMCLK=DCO which is set to 8 MHz and ACLK=VLOCLOCK which is 10KHz. Interrupt is generating but if i will use CCR0 then only it will be proper if i am using CCR1 or CCR2 it will generate interrupt independent of compare value i.e 35KHz
