Real-time output port
The INTC10 and INTC11 become output triggers of the real-time output port. In the macro service for them, the
next output pattern and interval can be set simultaneously. Therefore, the INTC10 and INTC11 can control 2
system stepping motor independently. Also, they can be applied to control a PWM or DC motor, etc.
Whenever the macro service request INTC10 is generated, the pattern and timing are transferred to P0L and
CR10, respectively. When the contents of the TM1 match with the contents of the CR10, the next INTC10 is
generated and the contents of the P0L are sent to the output latch. If T
n
(last byte) is sent to CR10, a vectored
interrupt request INTC10 is generated.
The same operation is available for INTC11 (differences: CR10

CR11, P0L
→
P0H, P00-P03
→
P04-P07).
