instructions
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.
