Revision History
10. P2.7 (CLKOUT)
6. EPA Timer RESET/Write Conflict
7. Valid Time Matches
8. Write Cycle during Reset
9. Indirect Shift Instruction
If the user writes to the EPA timer at the same time that the timer is reset, it is indeterminate
which will take precedence. Users should not write to a timer if using EPA signals to reset it.
The timer must increase/decrease to the compare value for a match to occur. A match does not
occur if the timer is loaded with a value equal to an EPA compare value. Matches also do not
occur if a timer is reset and 0 is the EPA compare value.
If RESET occurs during a write cycle, the contents of the external memory device may be
corrupted.
The upper 3 bits of the byte register holding the shift count are not masked completely. If the
shift count register has the value 32 c n, where n e 1, 3, 5, or 7, the operand will be shifted 32
times. This should have resulted in no shift taking place.
P2.7 (CLKOUT) does not operate in open drain mode.
Revision
b. Configured as Push/Pull, PxIO as ‘‘0’’.
a. Written to PxREG as ‘‘1’’ or ‘‘0’’.
c. Configured as LSIO.

This configuration will effectively strap the pin either high or low. DO NOT Configure as
Open Drain output ‘’1’’, or as an Input pin. This device is CMOS.

Removed the 87C196KQ and 87C196JQ products and related
information from datasheet.
Added 87C196CA product and related information to datasheet.
The 87C196JV datasheet status has been moved from “Product
Preview” to that of “no marking.
A ”by design” note was added to the T
Design Considerations section, the #7.CLKOUT design consideration
was corrected.
Only the two most current revision histories of this datasheet were
retained in the datasheet revision history section.
