Function
1 → (<bit-No.> of <EAd>)
Sets a specified bit in the contents of a general register or a memory
location to 1. The bit number is specified by 3-bit immediate data or the
lower three bits of a general register.
if cc, 1 → (<bit-No.> of <EAd>)
If the specified condition is satisfied, this instruction sets a specified bit in
a memory location to 1. The bit number can be specified by 3-bit
immediate data, or by the lower three bits of a general register. The Z flag
status can be specified as a condition.
0 → (<bit-No.> of <EAd>)
Clears a specified bit in the contents of a general register or a memory
location to 0. The bit number is specified by 3-bit immediate data or the
lower three bits of a general register.
if cc, 0 → (<bit-No.> of <EAd>)
If the specified condition is satisfied, this instruction clears a specified bit
in a memory location to 0. The bit number can be specified by 3-bit
immediate data, or by the lower three bits of a general register. The Z flag
status can be specified as a condition.
∼ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)
Inverts a specified bit in the contents of a general register or a memory
location. 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 the contents of a general register or a memory
location 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 the contents of a general
register or a memory location and stores the result in the carry flag. The
bit number is specified by 3-bit immediate data.
C ∧ [∼ (<bit-No.> of <EAd>)] → C
ANDs the carry flag with the inverse of a specified bit in the contents of a
general register or a memory location 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 the contents of a general register
or a memory location and stores the result in the carry flag. The bit
number is specified by 3-bit immediate data.
