SBX SBX X-Register AND with accu, SBC memory, result into X-Register SBX N V - B D I Z C Operation: X <- (X)/\(A) - M / . . . . . / / +----------------+-----------------------+---------+---------+----------+ | Addressing Mode| Assembly Language Form| OP CODE |No. Bytes|No. Cycles| +----------------+-----------------------+---------+---------+----------+ | Immediate | SBX #$FF | $CB | 2 | 2 | +----------------+-----------------------+---------+---------+----------+ Note: Performs CMP and DEX at the same time, so that the subtraction ignores flags 'C' and 'D' (like CMP, unlike SBC). Also known as AXS.
