1 Hz Interrupt Generator
Description
This is a special oscillator with supervisor system. Three inputs are used to control the oscillator. SENSE (PIN4) controls
the voltage supply of the chip. If supply voltage decreases down to the threshold set by EX_VREF (PIN8), the chip
disables the oscillator and sets SMC_INICK to LOW. When the voltage is bigger than threshold set by EX_VREF is
detected on the SENSE pin, SMC_RST_N (PIN7) is set to HIGH with 20 ms delay and enables the oscillator.
MBL_PWRGD_MR_N (PIN3) is used for manual reset of SMC_RST_N. Use NMI_GATE (NMI_GATE) to disable the
oscillator.
