5. I/O Ports
input data should be externally held until the input data is read from outside or reading should be performed several
timer before processing. Figure 5-1 shows input/output timing examples.
timing cannot be recognized from outside, so that transient input such as chattering must be processed by the pro-
gram.
port.
The TMP86PM49UG has 8 parallel input/output ports (56 pins) as follows.
Each output port contains a latch, which holds the output data. All input ports do not have latches, so the external
External data is read from an I/O port in the S1 state of the read cycle during execution of the read instruction. This
Output data changes in the S2 state of the write cycle during execution of the instruction which writes to an I/O
Note: The positions of the read and write cycles may vary, depending on the instruction.
