91 / 247 page  ST72344xx, ST2345xx On-chip peripherals Doc ID 12321 Rev 6 91/247 A modification of the time base is taken into account at the end of the current period (previously set) to avoid an unwanted time shift. This allows to use this time base as a real- time clock. Bit 1 = OIE Oscillator interrupt enable This bit set and cleared by software. 0: Oscillator interrupt disabled 1: Oscillator interrupt enabled This interrupt can be used to exit from Active-halt mode. When this bit is set, calling the ST7 software HALT instruction enters the Active-halt power-saving mode. Bit 0 = OIF Oscillator interrupt flag This bit is set by hardware and cleared by software reading the MCCSR register. It indicates when set that the main oscillator has reached the selected elapsed time (TB1:0). 0: Timeout not reached 1: Timeout reached Caution: The BRES and BSET instructions must not be used on the MCCSR register to avoid unintentionally clearing the OIF bit. MCC beep control register (MCCBCR) Reset value: 0000 0000 (00h) Bits 7:2 = Reserved, must be kept cleared. Bits 1:0 = BC[1:0] Beep control These 2 bits select the PF1 pin beep capability. Table 42.
