effect, and reading them always returns zero. Reserved bits may be in use and should not be changed from the values given in parentheses.
Writing values other than those shown in parenthesis to reserved bits may have undesirable side effects and must be avoided.
Non-volatile bits are shaded in dark gray. Non-volatile bits are backed-up during power failures if the system includes a battery connected to the
VBAT pin.
This table lists only the SFR registers that are not generic 8051 SFR registers. Bits marked with † (e.g. UMUX_E
