Table 54. Previous received byte
1) Access via UART service and SPI possible. In case of hard reset the register is reset to the hard reset value.
UART Byte Transmitter
TXD idle-level in any other mode but KNX Analog Mode is "1".
The UART transmitter has a baud rate deviation of less than 1% during byte frame transmission. Subsequent
bytes may be transmitted without a break.
