Reset Value = XXXX 00X0
Not bit addressable
User software should not write 1s to reserved bits. These bits may be used in future 8051 family
products to invoke new feature. In that case, the reset value of the new bit will be 0, and its
active value will be 1. The value read from a reserved bit is indeterminate.
