unable to hit interrupt function when value is written in register in debug mode.

I am using "TM4C123GH6PM" and written UART program using interrupt. When any key is pressed it will write the character back.
The issue is i am unable to see the interrupt hit when i change the value in register "UART0_UART_DR" through register view in debug mode, but when i enter any key using hyper terminal it is working as expected.
