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.
