TMP86CH09NG
5. I/O Ports
The TMP86CH09NG have 4 parallel input/output ports as follows.
Each output port contains a latch, which holds the output data. All input ports do not have latches, so the external
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.
External data is read from an I/O port in the S1 state of the read cycle during execution of the read instruction. This
timing cannot be recognized from outside, so that transient input such as chattering must be processed by the pro-
gram.
Output data changes in the S2 state of the write cycle during execution of the instruction which writes to an I/O
port.
Note: The positions of the read and write cycles may vary, depending on the instruction.
