MSP430FR5969: Interrupt services routine

Hi,

I am using TIMERB0 to create a one-second interrupt and in this service routine, an operation takes place which can take 10ms intervals. I am receiving data through UCA1 at 32us intervals continuously,thus in this 10ms duration I can receive 312 UCA1 receive interrupts, will all UCA1 interrupts will be in que?

There is only one. Just like there can be only one character in RXBUF. If you don't read that before the next character arrives, the data is lost. So that excessively long ADC interrupt is trouble.
