Function
BSET B 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
BCLR B 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
BNOT B ~ (<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
BTST B ~ (<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
BAND B 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
BIAND B 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
BOR B 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
BIOR B 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
