4.0 Pin Descriptions
(Continued)
Note:
For compatibility with existing software written for COP888xG devices
and with existing Mask ROM devices, a read of the Port I input pins
(address xxD7) will return the same data as reading the Port F input
pins (address xx96). It is recommended new applications which will go
to production with the COP8SGx use the Port F addresses. Note that
compatible ROM devices contains the input only Port I instead of the
bi-directional Port F.
Port D is an 8-bit output port that is preset high when RESET
goes low. The user can tie two or more D port outputs
(except D2) together in order to get a higher drive.
Note:
Care must be exercised with the D2 pin operation. At RESET, the
external loads on this pin must ensure that the output voltages stay
above 0.7 V
to prevent the chip from entering special modes. Also
keep the external loading on D2 to less than 1000 pF.
