Evaluation Chip Set and
ZTAT
/Mask ROM Product Differences
As shown in figure 27, the NMOS intermediate-voltage open drain pin circuit in the evaluation chip set
differs from that used in the ZTAT
microcomputer and built-in mask ROM microcomputer products.
Please note that although these outputs in the ZTAT
microcomputer and built-in mask ROM
microcomputer products can be set to high impedance by the combinations shown in table 23, these outputs
cannot be set to high impedance in the evaluation chip set.
