Function
¬ (<bit-No.> of <EAd>)
1
Tests a specified bit in a general register or memory, then
sets the bit to “1.” The bit is specified by a bit number
given in immediate data or a general register.
¬ (<bit-No.> of <EAd>)
0
Tests a specified bit in a general register or memory, then
clears the bit to “0.” The bit is specified by a bit number
given in immediate data or a general register.
¬ (<bit-No.> of <EAd>)
Tests a specified bit in a general register or memory, then
inverts the bit. The bit is specified by a bit number given
in immediate data or a general register.
¬ (<bit-No.> of <EAd>)
Tests a specified bit in a general register or memory. The
bit is specified by a bit number given in immediate data or
a general register.
