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