        NOTES: 1. Pulses on the UART receive input (UCxRX) shorter than the UART receive deglitch time are suppressed. To ensure that pulses are
        correctly recognized their width should exceed the maximum specification of the deglitch time.

        For the slave’s parameters tSU,SI(Slave) and tVALID,SO(Slave) refer to the SPI parameters of the attached slave.
        2. Specifies the time to drive the next valid data to the SIMO output after the output changing UCLK clock edge. Refer to the timing
        diagrams in Figure 21 and Figure 22.
        3. Specifies how long data on the SIMO output is valid after the output changing UCLK clock edge. Negative values indicate that the
        data on the SIMO output can become invalid before the output changing clock edge observed on UCLK. Refer to the timing diagrams
