To overcome this we can use DMA controller of PIC32 which will take care of the data transmission over UART without disturbing the CPU. When I use 2 interrupts lets say UART and 1 timer the microcontroller is working fine but when I use UART and 2 timer interrupts the microcontroller freezes. The PIC32 has a DMA (direct memory access) module that allows the data transfer in the PIC32 without CPU intervention during data transfer - thus freeing up CPU to perform other tasks while the data is transferred). This is a great way to debug your program, as you can quickly print some text out, as well as send data to.
