The TS80C54/58X2 has 2 software-selectable modes of reduced activity for further reduction in

power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the

interrupt system are still operating. In the power-down mode the RAM is saved and all other

functions are inoperative.
