On the fly configuration change

[Milan]

Hi Team,

In my application UART is used. I need to send parity bit based on particular responses that I need to send to the device connected to UART.
Can I change configuration of UART on-the-fly for this? In datasheet it is mentioned that parity checking is supported.
What to do if I need to send 0x00 data with parity bit 1?

Regards, Milan Joshi

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.

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
