If you are using app_uart library, then an interrupt will be generated with any error and in the interrupt handler, the error bit will be cleared automatically. You do not have to do anything for it.

I am getting parity error as expected. how to clear parity error bit. I know by writing 1 it will get cleared but is there any API to do this!

Parity will be generated and checked only if the Parity is enabled. So parity error is not generated if it is not enabled. What do you mean by 9th bit set? If no parity is used then the stop bit is 10th bit and it should be high else framing error will be generated and set in ERRORSRC register

Can you tell me in which case parity error will be generated? If I configure No Parity option and data with 9th bit set is received, will it give parity error? My device address comes with 9th bit set and normal data is received without 9th bit.

nRF51 chips only have even parity configuration. You can either disable it or enabled but you cannot change it to odd parity.

I just tested it and you can just change the parity on the fly. At least my logic analyzer is happy with the change.
