SBC TSX TXS Instructions 6800 6502
The implementation of the borrow bit for the 6502 is different from the 6800 in order that arithmetic operations on the 6502 would give more consistent results |
What is subtract with carry 6502?
The 6502 has a SBC operation (subtract with carry) that subtracts two numbers and also subtracts the borrow bit.
If the (unsigned) operation results in a borrow (is negative), then the borrow bit is set.
However, there is no explicit borrow flag - instead the complement of the carry flag is used.Is 6502 big endian?
The 6502 is a little-endian 8-bit processor with a 16-bit address bus.
The original versions were fabricated using an 8 µm process technology chip with a die size of 3.9 mm × 4.3 mm (advertised as 153 mils × 168 mils), for a total area of 16.6 mm2.
