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 three 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 three 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
three 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 three 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
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
C ∨ (<bit-No.> of <EAd>) → C
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
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
