3.3.2 Serial IN Communication

Serial IN communication is activated by the serial receive interrupt and executed by the ActSerialIn function. The

sample program stores serially-received data in the RAM for the bulk IN transfer. When the RAM is full, the sample

program transmits Xoff in serial communication to disable the serial IN communication.

Figure 3.8 shows an operation
