34 / 104 page  ST6208C/ST6209C/ST6210C/ST6220C 34/104 6.3 STOP MODE STOP mode is the lowest power consumption mode of the MCU (see Figure 22). The MCU goes into STOP mode as soon as the STOP instruction is executed. This has the follow- ing effects: – Program execution is stopped, the microcontrol- ler can be considered as being “frozen”. – The contents of RAM and the peripheral regis- ters are kept safely as long as the power supply voltage is higher than the RAM retention voltage. – The oscillator is stopped, so peripherals cannot work except the those that can be driven by an external clock. Exit from STOP Mode The MCU remains in STOP mode until one of the following events occurs: – RESET (Watchdog, LVD or RESET pin) – A peripheral interrupt (assuming this peripheral can be driven by an external clock) – An external interrupt (I/O port, NMI) In all cases a delay of 2048 clock cycles (f INT) is generated to make sure the oscillator has started properly. The Program Counter then points to the starting address of the interrupt or RESET service routine (see Figure 21). STOP Mode and Watchdog When the Watchdog is active (hardware or soft- ware activation), the STOP instruction is disabled and a WAIT instruction will be executed in its place unless the EXCTNL option bit is set to 1 in the op- tion bytes and a a high level is present on the NMI pin. In this case, the STOP instruction will be exe- cuted and the Watchdog will be frozen. Figure 21.
