when set, most of the clocks will be enabled.
when set, enable read_access for MASK ROM
when set, P1.4 will output system clock used by on chip TB8032. If chip is configured as double system
clock speed, it output the x2 system clock.
when set, enable MASK ROM test mode.
when set, 32k clock will replace with 13.824 system clock for speed up testing.
