User’s Manual
Z80 Status Indicator Flags
The flag registers (F and F') supply information to the user about the status
of the Z80 at any given time. The bit positions for each flag is listed below:
Each of the two flag registers contains 6 bits of status information that are
set or cleared by CPU operations. (Bits 3 and 5 are not used.) Four of these
bits (C, P/V, Z, and S) may be tested for use with conditional
or
for BCD arithmetic.
Carry Flag
The Carry Flag (C) is set or cleared depending on the operation performed.
For
generate a Borrow, the Carry Flag sets. The Carry Flag is reset by an
instruction that does not generate a Carry, and by a
does not generate a Borrow. This saved Carry facilitates software routines
