Revision: 1.3
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:
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.
