NOTES FOR MOVX CHARACTERISTICS USING STRETCH MEMORY CYCLES
§ tMCS is a time period related to the Stretch memory cycle selection. The following table shows the value of tMCS
for each Stretch selection.
§ CST is the stretch cycle value as determined by the MD2, MD1, & MD0 bits of the CKCON register.
