7.3.2 Method of transmission
Figures 7.3.1 shows an initial setting example for relevant registers when transmitting. Transmission is
started when all of the following conditions (
satisfy conditions
<Precondition>
The CLK
Note: When an internal clock is selected, above precondition is ignored.
<Transmission conditions>
Note: When the CTS function is not selected, this condition is ignored.
When using interrupts, it is necessary to set the relevant register to enable interrupts. For details, refer to
“Chapter 4. INTERRUPTS.”
Figure 7.3.2 shows writing data after start of transmission, and Figure 7.3.3 shows detection of transmission’s
completion.
Transmission is enabled (transmit enable bit = “1”).
Transmit data is present in the UARTi transmit buffer register (transmit buffer empty flag = “0”)
