Function
1 → (<bit-No.> of <EAd>)
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 3 bits of a general
register.
0 → (<bit-No.> of <EAd>)
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 3 bits of a general
register.
¬ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)
Inverts a specified bit in a general register or memory operand. The bit
number is specified by 3-bit immediate data or the lower 3 bits of a general
register.
¬ (<bit-No.> of <EAd>) → Z
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 3 bits of a general register.
C ∧ (<bit-No.> of <EAd>) → C
ANDs the carry flag with 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
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.
