NOTES FOR MOVX CHARACTERISTICS:
1. All parameters apply to both commercial and industrial temperature operation unless otherwise noted.
2. CST is the stretch cycle value as determined by the MD2, MD1, & MD0 bits of the CKCON register.
t_MCS is a time period determined by the stretch cycle value, shown in the following table.
