REV 1.1
The negative bit is set when the result of the last arithmetic operation, logical
operation, or data manipulation was negative. (Bit 7 of the result was a logical
one.)
The negative bit can also be used to check an often tested ag by assigning the
ag to bit 7 of a register or memory location. Loading the accumulator with the
contents of that register or location then sets or clears the negative bit according
to the state of the ag.
3.6.4 Zero Bit (Z-Bit)
The zero bit is set when the result of the last arithmetic operation, logical
operation, data manipulation, or data load operation was zero.
3.6.5 Carry/Borrow Bit (C-Bit)
The carry/borrow bit is set when a carry out of bit 7 of the accumulator occurred
during the last arithmetic operation, logical operation, or data manipulation. The
carry/borrow bit is also set or cleared during bit test and branch instructions and
during shifts and rotates. This bit is neither set by an INC nor by a DEC instruction.
