24. MASK Option (MC80C0104/0204)
The MC80C0104/0204 has several MASK option which
configures the package type or use of some special features
of the device. The Mask option of the MASK order sheet
should be checked to select device configuration such as
package type, Oscillation selection, oscillation noise pro-
