UART handles communications by means of character-by-character synchronization. The transmission
side and the reception side are independent of each other, so full-duplex communication is possible. The
following is an overview of the clock-asynchronous serial I/O usage.
(1) Transmission/reception format
Figure 2.5.1 shows the transmission/reception format, and Table 2.5.1 shows the names and func-
tions of transmission data.
Name
Transfer data length : 7 bits
Transfer data length : 8 bits
Transfer data length : 9 bits
A 1-bit “L” signal to be added immediately before character bits.
This bit signals the start of data transmission.
A signal to be added immediately after character bits so as to increase data
reliability. The level of this signal so varies that the total number of 1's in
character bits and this bit always becomes even or odd depending on which
parity is chosen, even or odd.
Either 1-bit or 2-bit “H” signal to be added immediately after character bits (after
the parity bit if parity is checked). This / they signals the end of data
transmission.
Transmission data set in the UARTi transmit buffer register.
