The differences between the PCA84C122 and the other devices are specified in Chapter 3. Figure 2 shows the general block diagram of the device. The 84CXXX core plus 8 kbytes ROM and 64 bytes RAM has the same function as described in the PCF84CXXX family description (see “Data Handbook IC14” ). When the transmitter is not in use the microcontroller is in Stop mode and the oscillator is halted. The AND gate connected to the Port 1 (P10 to P17) lines provides the wake-up to end the Stop mode. The Hardware Modulator produces pulse bursts...
