63.7.4.2.2 Receive NACK Inhibit

The USART can be configured to inhibit an error. This is done by writing a ‘1’ to FLEX_US_MR.INACK. In this case, no error signal is driven on the I/O line even if a parity bit is detected.

Moreover, if INACK = 1, the erroneous received character is stored in the Receive Holding register as if no error occurred, and the RXRDY bit rises.
