Function
1 → (<bit-No.> of <EAd>)
Sets a specified bit in a general register or memory to "1." The bit
is specified by a bit number, given in 3-bit immediate data or the lower
three bits of a general register.
0 → (<bit-No.> of <EAd>)
Clears a specified bit in a general register or memory to "0." The
bit is specified by a bit number, given in 3-bit immediate data or the
lower three bits of a general register.
¬ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)
Inverts a specified bit in a general register or memory. The bit is
specified by a bit number, given in 3-bit immediate data or the lower
three bits of a general register.
¬ (<bit-No.> of <EAd>) → Z
Tests a specified bit in a general register or memory and sets or
clears the Z flag accordingly. The bit is specified by a bit number,
given in 3-bit immediate data or the lower three bits of a general
register.
C ∧ (<bit-No.> of <EAd>) → C
ANDs the C flag with a specified bit in a general register or
memory.
C ∧ [¬ (<bit-No.> of <EAd>)] → C
ANDs the C flag with the inverse of a specified bit in a general
register or memory.
The bit number is specified by 3-bit immediate data.
C ∨ (<bit-No.> of <EAd>) → C
ORs the C flag with a specified bit in a general register or memory.
C ∨ [¬ (<bit-No.> of <EAd>)] → C
ORs the C flag with the inverse of a specified bit in a general
register or memory.
The bit number is specified by 3-bit immediate data.
