APPLICATION
2.3 Serial I/O
Figure 2.3.21 shows a setting of serial I/O related registers, and Figure 2.3.22 shows a setting of serial
I/O transmission data.
Fig. 2.3.22 Setting of serial I/O transmission data [Output of serial data]
Fig. 2.3.21 Setting of serial I/O related registers [Output of serial data]
Set a transmission data.
Check that transmission of the previous data is
completed before writing data (bit 3 of the
Interrupt request register 1 is set to “1”).
