2.9.2 Carry flag (CY)
The carry flag is set (to 1) in the following cases:
If the ANL instruction or the XRL instruction is executed when bit 3 of the accumulator is “1” and bit 3 of the
operand is “1”.
If the RL instruction or the RLZ instruction is executed when bit 3 of the accumulator is “1”.
If the INC instruction or the SCAF instruction is executed when the value of the accumulator is 0FH.
The carry flag is cleared (to 0) in the following cases:
If the ANL instruction or the XRL instruction is executed when at least either bit 3 of the accumulator or bit
3 of the operand is “0”.
If the RL instruction or the RLZ instruction is executed when bit 3 of the accumulator is “0”.
If the INC instruction or the SCAF instruction is executed when the value of the accumulator is other than 0FH.
If the ORL instruction is executed.
When Data is written to the accumulator by the MOV instruction or the IN instruction.
