- Z-flag
Z-flag is set when zero is the result of operations; it is
cleared in other cases.
- V-flag
V-flag is set when a two’s complement overflow occurs as a
result of operations; it is reset when an overflow does not
occur.
- C-flag
C-flag is set when a carry or a borrow out of bit 7 is generated
as a result of operations; it is cleared in other cases. When
the shift instruction is executed, the value of the C-flag is
shifted out.
General-purpose register..... 8-bit length register where data are stored.
8-bit general-purpose registers are provided in the register banks in the
memory for storing data. Eight registers are provided per bank for and up
to 16 banks can be used for MB89953 (8 banks are provided in MB89951,
32 banks are provided in MB89P955 and MB89PV950).
The register bank pointer (RP) indicates the currently-used bank.
Note: The register banks are as follows depend on RAM area.
MB89951
0100H to 013FH 8 banks
MB89953
0100H to 017FH 16 banks
MB89P955
0100H to 01FFH 32 banks
MB89PV950 0100
H to 01FFH
32 banks
