1101 TC Test Bit Set
1110 NBIO BIO Input Equal To Zero
1111 UNC Unconditional
If the specified condition being tested is true, then the 8-bit zero extended
constant is stored in the location pointed to by the "loc16" addressing mode:
if(COND = true) [loc16] = 0:8bit;
Note: Addressing modes are not conditionally executed; therefore, if an addressing mode
performs a pre- or post-modification, it will execute regardless of whether the condition
is true or not.
If (COND = true AND loc16 = @AX), then after the move AX is tested for a
negative condition. The negative flag bit is set if bit 15 of AX is 1, otherwise it
is cleared.
If (COND = true AND loc16 = @AX), then after the move, AX is tested for a
zero condition. The zero flag bit is set if AX = 0, otherwise it is cleared.
If the V flag is tested by the condition, then V is cleared.
