5.9 Real-Time Output Port
Data set previously in the real-time output buffer register is transferred to the output latch by hardware concurrently
with timer interrupt or external interrupt generation in order to output off-chip. This is a real-time output function. Pins
used to output off-chip are called real-time output ports.
By using a real-time output port, a signal with no jitter can be output. This is most applicable to control of stepper
motors, etc.
