7.2.1 UARTi transmit/receive mode register
Figure 7.2.2 shows the structure of UARTi transmit/receive mode register. The serial I/O mode select bits
is used to select UARTi’s operating mode. Bits 4 to 6 are described in the section “7.4.2 Transfer data
format,” and bit 7 is done in the section “7.4.8 Sleep mode.”
