330 / 408 page  Timebase Module (TBM) Technical Data MC68HC908GR8 — Rev 4.0 330 Timebase Module (TBM) MOTOROLA 21.4 Functional Description NOTE: This module is designed for a 32.768 kHz oscillator. This module can generate a periodic interrupt by dividing the crystal frequency, CGMXCLK. The counter is initialized to all 0s when TBON bit is cleared. The counter, shown in Figure 21-1, starts counting when the TBON bit is set. When the counter overflows at the tap selected by TBR2:TBR0, the TBIF bit gets set. If the TBIE bit is set, an interrupt request is sent to the CPU. The TBIF flag is cleared by writing a 1 to the TACK bit. The first time the TBIF flag is set after enabling the timebase module, the interrupt is generated at approximately half of the overflow period. Subsequent events occur at the exact period.
