| 65c816 native mode | N | V | M | X | D | I | Z | C |
| 6502 emulation mode | N | V | . | B | D | I | Z | C |
PLP (PulL status flags) is a 65x instruction that pulls the 8-bit value at the top of the stack into the status register. The stack pointer is incremented before the byte is pulled.
The emulation mode bit is not on the stack so it does not get pulled.
