Table 15. FLAGS Register [Group/Bank F0h, Register C (R252)] (Continued)
Register Pointer (RP)
Z8 instructions can access registers directly or indirectly using either a 4-bit or 8-
bit address field. The upper nibble of the Register Pointer, as described in
Table 16, contains the base address of the active Working Register GROUP. The
lower nibble contains the base address of the Expanded Register File BANK.
When using 4-bit addressing, the 4-bit address of the working register (r0 to rF) is
combined with the upper nibble of the Register Pointer (identifying the WR
GROUP), thus forming the 8-bit actual address.

Used for BCD arithmetic—after a
subtraction, the flag is set to 1;
following an addition, it is cleared to 0
Set to 1, whenever an addition
generates a “carry out” of bit position
