UART7 or RX7

[WaSt_4596866]

I have been using the UART8 module to send and receive standard 8 bit wide serial communication on the CY8C29466-24PXI.

Now I need to receive 7 bit wide serial communication. Is there any way to reconfigure the standard UART8 or RX8 to UART7 or RX7 to receive standard 7 bit wide serial communication?

Have you any ideas? Thanks

Kindly refer to Transmitting 7 data bits + 1 Parity Bit using UART.

Thanks for the link - but my problem is the receiving side. What will

happen when a RXD programmed for 8 bit receives only 7 bits?

Will it be sufficient to mask the 8 bits with 7Fh (0111 1111) to get the

seven relevant bits?

Thanks for your support

I think it should be OK if you mask with 7Fh. It should receive OK, if byte to byte time from the transmitter is more than two bits or three bits wide in time.

Best regards,
