Function
1 â (<bit-No.> of <EAd>)
Sets a specified bit in a general register or memory to â1.â The bit is
specified by a bit number, given in 3-bit immediate data or the lower
three bits of a general register.
0 â (<bit-No.> of <EAd>)
Clears a specified bit in a general register or memory to â0.â The bit is
specified by a bit number, given in 3-bit immediate data or the lower
three bits of a general register.
¬ (<bit-No.> of <EAd>) â (<bit-No.> of <EAd>)
Inverts a specified bit in a general register or memory. The bit is
specified by a bit number, given in 3-bit immediate data or the lower
three bits of a general register
¬ (<bit-No.> of <EAd>) â Z
Tests a specified bit in a general register or memory and sets or clears
the Z flag accordingly. The bit is specified by a bit number, given in
3-bit immediate data or the lower three bits of a general register.
C ⧠(<bit-No.> of <EAd>) â C
ANDs the C flag with a specified bit in a general register or memory.
C ⧠[¬ (<bit-No.> of <EAd>)] â C
ANDs the C flag with the inverse of a specified bit in a general register
or memory.
The bit number is specified by 3-bit immediate data.
C ⨠(<bit-No.> of <EAd>) â C
ORs the C flag with a specified bit in a general register or memory.
C ⨠[¬ (<bit-No.> of <EAd>)] â C
ORs the C flag with the inverse of a specified bit in a general register or
memory.
The bit number is specified by 3-bit immediate data.
C â (<bit-No.> of <EAd>) â C
XORs the C flag with a specified bit in a general register or memory.
