REAL-TIME OUTPUT PORT
The real-time output port outputs the data stored in the buffer in synchronization with timer match interrupts
or external interrupts. A jitterless pulse output is obtained by means of this.
Therefore, it is most suitable for applications which output any pattern at any interval time. (Stepping motor open
loop control, etc.)
Port 0 and the buffer register are the core elements of the configuration, as shown in Fig. 3-3.
