facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism.
The fully static design of the TS80C51Rx2 allows to reduce system power consumption by
bringing the clock frequency down to any value, even DC, without loss of data.
The TS80C51Rx2 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.
