Evaluation Chip Set and
ZTAT
/Mask ROM Product Differences
As shown in figure 20, the NMOS intermediate breakdown 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.

An asterisk indicates that the value may be either 0 or 1 and has no influence on circuit operation.
This applies to the ZTAT
