AT/TS8xC54/8X2
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.
