Errata
Production Version 00
1. Functional differences between IA6805E2 and Harris and Motorola Versions: Stop mode on
IA6805E2 will not halt oscillator. Recovery from stop will be quicker.
2. Observations:
A. Original data sheets for Motorola and Harris are inconsistent when describing timer input mode 2.
Original parts and InnovASIC will AND together the timer input with the inverse of the internal
clock (AS).
B. Original Harris part would unpredictably “pre-increment” timer counter when writing to timer
registers. IA6805E2 will not.
C. Original Harris part displays incorrect address on external pins during intermediate cycles (not a
functional problem) of multi-cycle instructions when accessing memory at page boundaries.
IA6805E2 will not.
D. Execution of illegal op-codes on the IA6805E2 will force a system reset. On the original Harris
and Motorola parts, execution of illegal op-codes would produce unpredictable results.
