20.5.9 - Memory Cycle Variables
The tables below use three variables which are derived from the BUSCONx registers and which
represent the special characteristics of the programmed memory cycle. The following table describes
how these variables are computed.
20.5.10 - Multiplexed Bus
VDD =5V ±10%, VSS = 0V, for Q6 version : TA = -40, +85°C and for Q2 version TA = -40, +125°C, CL = 100pF,
ALE cycle time = 6 TCL + 2tA +tC +tF (120ns at 25MHz CPU clock without wait states),
unless otherwise specified.
