Enter Power Down Mode
This instruction causes the part to enter the power down mode. In this
mode, all peripherals and the CPU are powered down until the part is
externally reset. To insure that this instruction is not accidentally exe-
cuted, it is implemented as a protected instruction. To further control the
action of this instruction, the PWRDN instruction is only enabled when the
non-maskable interrupt pin (NMI) is in the low state. Otherwise, this
instruction has no effect.
