10.1 Function of Real-Time Output Port
concurrently with timer interrupts or external interrupt request generation, then output externally. This is called the
real-time output function. The pins that output data externally are called real-time output ports.
for applications where an arbitrary pattern is output at an arbitrary interval (open-loop control of a stepper motor, etc.).
the real-time output port in 1-bit units.
10.2 Configuration of Real-Time Output Port
180
Data set previously in the real-time output buffer register can be transferred to the output latch by hardware
By using the real-time output port, it is possible to output a signal with no jitter. Therefore, this is most suitable
Also, it is possible to perform PWM modulation at a specified pin for the output pattern.
The PD780988 Subseries has the following 2 channels of real-time output ports on chip. It is possible to specify
• 8 bits
• 6 bits
A real-time output port includes the following hardware.
