Reserved.
Set this bit to 1 will reset TT1 to 0, after bit 7 reset,
CLR_TT1 will deassert automatically.
Set this bit to 1 will reset TT2 to 0, after bit 6 reset,
CLR_TT2 will deassert automatically.
Write 1, enable battery voltage monitor. Write 0,
disable battery voltage monitor. If enable this bit, the
monitor value is valid after one monitor cycle.
