Table 2.6  Bit Manipulation Instructions (1) 
Instruction Size* 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 
BIAND 
B 
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. 
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 
BIOR 
B 
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. 
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. 
Note:  *  Refers to the operand size. 
 B: Byte
