Flag registers and their bit positions in PSW:

7	6	5	4	3	2	1	0
S	Z	K	A	-	P	V	C

C: Carry flag; set to carry out of bit 7 in result
V: Undocumented signed overflow flag^* (8085 only, on 8080 bit is always 1 in PSW)
P: Parity flag; set if the number of bits in the result is even, and reset if it's odd
No flag, bit is always 0 in PSW
A: Auxiliary Carry (A_C) flag; set to carry out of bit 3 in result
K: Undocumented signed Underflow Indicator (UI/X5) and comparison flag^* (8085 only, on 8080 bit is always 0 in PSW)
Z: Zero flag; set if the result was zero, reset otherwise
S: Sign flag; set to bit 7 of result

Flags affected are always shown in the PSW bit order: SZKAPVC. If a flag is marked by "0" it means it is reset after the instruction. If it is marked by "1" it is set. If it is marked by "-" it is not changed. If it is marked by its letter, the corresponding flag is affected by the instruction.

Blue flags are only affected on 8085. For some instructions that affect flags differently on 8080 and 8085, there are two flag status lines.

The duration of conditional calls and returns is different when the branch is taken or not. This is indicated by two numbers separated by “/”. The lower number (on the left side of “/”) is the duration of the instruction when there is no branch, and the higher number (on the right side of “/”) is the duration of the instruction when the branch is taken.
