Table 63 lists the functions of the bits in the PSW register.
Bit
PSW.7
Function
CY - Carry flag. Set to 1 when last arithmetic operation resulted in a carry (during
addition) or borrow (during subtraction); otherwise cleared to 0 by all arithmetic
operations.
AC - Auxiliary carry flag. Set to 1 when last arithmetic operation resulted in a carry into
(during addition) or borrow from (during subtraction) the high-order nibble; otherwise
cleared to 0 by all arithmetic operations.
F0 - User flag 0. Bit-addressable, general purpose flag for software control.
RS1 - Register bank select bit 1. Used with RS0 to select a register blank in internal
RAM.
RS0 - Register bank select bit 0, decoded as:
RS1 RS0 Bank selected
0 0 Register bank 0, addresses 0x00-0x07
0 1 Register bank 1, addresses 0x08-0x0F
1 0 Register bank 2, addresses 0x10-0x17
1 1 Register bank 3, addresses 0x18-0x1F
PSW.6
PSW.5
PSW.4
PSW.3
PSW.2
OV - Overflow flag. Set to 1 when last arithmetic operation resulted in a carry (addition),
borrow (subtraction), or overflow (multiply or divide); otherwise cleared to 0 by all
arithmetic operations.
F1 - User flag 1. Bit-addressable, general purpose flag for software control.
P - Parity flag. Set to 1 when modulo-2 sum of 8 bits in accumulator is 1 (odd parity);
cleared to 0 on even parity.
Table 63 PSW Register – SFR 0xD0.
