Determines if any of the specified bits in a value are clear according to a specified bit mask.
Files
lib_def.h
Prototype
DEF_BIT_IS_CLR_ANY(val, mask);
Arguments
val
Value to test if any of the specified bits are clear.
mask
Mask of bits to check if clear in the value.
Returned Value
DEF_YES
If any of the bits in the bit mask are clear in val;
DEF_NO
if all the bits in the bit mask are set in val.
Required Configuration
None.
Notes / Warnings
val and mask should be unsigned integers. NULL mask (i.e., mask of value 0) allowed; returns DEF_NO since no mask bits specified.
Example Usage
CPU_INT16U alarms;
CPU_INT16U alarms_mask;
CPU_INT16U alarms_clr;
alarms = 0x07F0u;
alarms_mask = DEF_BIT_04 | DEF_BIT_03;
alarms_clr = DEF_BIT_IS_CLR_ANY(alarms, alarms_mask);
