3800 GROUP USER’S MANUAL
Control procedure :
Control in the master unit
After a setting of the related registers is completed as shown in Figure 2.3.33, in the master unit
transmission or reception of 1-byte data is started simply by writing transmission data to the
Transmit buffer register.
To perform the communication in the timing shown in Figure 2.3.25, therefore, take the timing into
account and write transmission data. Read out the reception data when the Serial I/O transmit
interrupt request bit is set to “1,” or before the next transmission data is written to the Transmit
buffer register.
A processing example in the master unit using timer interrupts is shown below.
