Notes: (1) DDD or SSS. B 000. C 001. D 010. E 011. H 100. L 101. Memory 110. A 111.
(2) Two possible cycle times, (6/12) indicate instruction cycles dependent on
condition flags.
Precautions for operation
(1) When the oscillation circuit is to be used, keep the RES input low until the oscillation is
sufficiently stabilized after power is turned on.
(2) When power is turned on, the output level (SOD etc.) is unknown before the equipment
is reset.
(3) Bug of MSM80C85A–2 at power down has fixed.
(4) Because Spike Noise would be output on HLDA, RESET OUT and CLK pins, depending
on the customers condition of usage; please take into account this issue at System Board
design.
