Memory Cycle Variables
The timing tables below use three variables which are derived from the BUSCONx
registers and represent the special characteristics of the programmed memory cycle.
The following table describes, how these variables are to be computed.
Note: Please respect the maximum operating frequency of the respective derivative.
