Table 16.7 Registers to be Used and Settings in UART

NOTES:
Table 16.7 lists registers to be used and settings. Tables 16.8 to 16.10 list pin settings. When UARTi (i=0
to 4) operation mode is selected, the TxDi pin outputs an "H" signal before transfer is started (the TxDi pin
is in a high-impedance state when the N-channel open drain output is selected). Figure 16.14 shows an
example of a transmit operation in UART mode. Figure 16.15 shows an example of a receive operation in
UART mode.
