6.4 OPERATION
into the output latch and output to the port 0 pins in synchronization with the generation of one of the trigger conditions shown
in Table 6-2.
can be selected as the output trigger generation source. In this case, the port 0 pin output data can be changed to the P0H and
P0L values using the value set in the CR10, CR11 beforehand as the timing interval. Combining this real-time output port function
with the macro service function enables the port 0 output pin output data to be changed sequentially at any interval time (see
20.8 MACRO SERVICE FUNCTION).
with an external event.
162
When the port 0 function is specified as the real-time output port, the port 0 buffer register (P0H, P0L) contents are fetched
For example, the timer/counter 1 timer register 1 (TM1) and compare register (CR10, CR11) match signal (INTC10, INTC11)
If the external interrupt pin (INTP0) is selected as the output trigger source, port 0 output can be obtained in synchronization
