A 6502 instruction that shifts all bits in the A register or a memory location to the left, moving bit 7 into the carry and the old carry into bit 0.
  • Function: N < 1 | C => N
  • Updates flags: S Z C
  • Opcode numbers:
    dp    $26
    impl  $2A  ; affects accumulator
    abs   $2E
    d,x   $36
    a,x   $3E

Don't forget to add 2 cycles to modes other than impl, as those modes are read-modify-write.
