75 / 138 page  ST7L15, ST7L19 75/138 LITE TIMER (cont’d) Bit 6 = ICF Input Capture Flag This bit is set by hardware and cleared by software by reading the LTICR register. Writing to this bit does not change the bit value. 0: No input capture 1: An input capture has occurred Note: After an MCU reset, software must initialize the ICF bit by reading the LTICR register Bit 5 = TB Timebase period selection This bit is set and cleared by software. 0: Timebase period = tOSC * 8000 (1ms @ 8 MHz) 1: Timebase period = tOSC * 16000 (2ms @ 8 MHz) Bit 4 = TB1IE Timebase Interrupt enable This bit is set and cleared by software. 0: Timebase (TB1) interrupt disabled 1: Timebase (TB1) interrupt enabled Bit 3 = TB1F Timebase Interrupt Flag This bit is set by hardware and cleared by software reading the LTCSR register. Writing to this bit has no effect. 0: No counter overflow 1: A counter overflow has occurred Bits 2:0 = Reserved LITE TIMER INPUT CAPTURE REGISTER (LTICR) Read only Reset Value: 0000 0000 (00h) Bits 7:0 = ICR[7:0] Input Capture Value These bits are read by software and cleared by hardware after a reset. If the ICF bit in the LTCSR is cleared, the value of the 8-bit up-counter will be captured when a rising or falling edge occurs on the LTIC pin. Table 15.
