'''PLD''' (PulL Direct page) is a [[65c816]] instruction that pulls the 16-bit value at the top of the [[stack]] into the [[direct page register]]. The low byte of this register is pulled first. After PLD completes, the [[stack pointer]] is pointing to where the high byte was, which becomes the next available stack location. | |||

PLD (PulL Direct page) is a 65c816 instruction that pulls the 16-bit value at the top of the stack into the direct page register. The low byte of this register is pulled first. After PLD completes, the stack pointer is pointing to where the high byte was, which becomes the next available stack location.
