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