  • Page 50: Stop Mode

    GMS81508/16 2.13.1. STOP Mode STOP Mode can be entered by STOP instruction during program execution. In STOP mode, oscillator is stopped to make all clocks stop, which leads to the mode requiring much less power consumption. All register and RAM data are preserved. Caution) NOP instruction have to be written more than 2 to next lines of STOP instruction.
  • Page 51 HYUNDAI MicroElectronics When release the STOP Mode, to secure oscillation stabilization time, we use Basic Interval Timer. So, before execution STOP instruction, we must select suitable B.I.T. clock for oscillation stabilization time. Otherwise, It is possible to release by only RESET input. Because STOP mode is released by interrupt, even if both of interrupt enable bit(IE) and interrupt request flag is "1", STOP mode can not be executed.
