Appendix A Electrical Characteristics
A.3.1.19
The maximum time to enable EPROM emulation is given by
where N
contain the latest active data and would need to be copied. The maximum possible is 33 (2048 EEE RAM
words /63 =32.5) although this is a highly unlikely scenario. The impact of a worst case brownout recovery
scenario is denoted by BWN = 2 for non brownout situations BWN =0.
