chattering must be processed by the program.

Instruction execution cycle
Instruction execution cycle
The TMP86FM48 has 8 parallel input/output ports (54 pins) as follows.
Each output port contains a latch, which holds the output data. All input ports do not have
External data is read from an I/O port in the S1 state of the read cycle during execution of the
Output data changes in the S2 state of the write cycle during execution of the instruction
Note: The positions of the read and write cycles may vary, depending on the instruction.
