While it is simple to assign a value to a byte, and there is special Boolean notation &B for assigning bits, the Bits() and NBits() function makes it simple to assign a few bits.

 

B = &B01111101 : how many zero’s are there?

This would make it more readable: B = NBits(1, 7)

You can read from the code that bit 1 and bit 7 are NOT set to 1.

It does not save code space as the effect is the same.

 

The NBITS() function will set all bits to 1 except for the specified bits.

It can only be used on bytes and port registers.

Valid bits are in range from 0 to 7.
