the bit masking setting confuse me, set a bit to 1 means disable preemption or 0 means disable preemption？
| enum Hwi_MaskingOption |  |
Shorthand interrupt masking options
| C synopsis | target-domain |
typedef enum Hwi_MaskingOption {
Hwi_MaskingOption_NONE,
Hwi_MaskingOption_ALL,
Hwi_MaskingOption_SELF,
Hwi_MaskingOption_BITMASK,
Hwi_MaskingOption_LOWER
} Hwi_MaskingOption;
VALUES
MaskingOption_NONE — No interrupts are disabled
MaskingOption_ALL — All interrupts are disabled
MaskingOption_SELF — Only this interrupt is disabled
MaskingOption_BITMASK — User supplies interrupt enable masks
MaskingOption_LOWER — All current and lower priority interrupts are disabled.
Only a few targets/devices truly support this masking option. For those that don't, this setting is treated the same as MaskingOption_SELF.
