62 / 126 page  Core Timer General Release Specification MC68HC705RC17 — Rev. 2.0 Core Timer TOFC — Timer Overflow Flag Clear When a 1 is written to this bit, CTOF is cleared. Writing a 0 has no effect on the CTOF bit. This bit always reads as 0. RTFC — Real-Time Interrupt Flag Clear When a 1 is written to this bit, RTIF is cleared. Writing a 0 has no effect on the RTIF bit. This bit always reads as 0. RT1 and RT0 — Real-Time Interrupt Rate Select These two bits select one of four taps from the real-time interrupt circuit. Refer to Table 8-1. Reset sets these two bits which selects the lowest periodic rate and gives the maximum time in which to alter these bits if necessary. Care should be taken when altering RT0 and RT1 if the time out period is imminent or uncertain. If the selected tap is modified during a cycle in which the counter is switching, an RTIF could be missed or an additional one could be generated. To avoid problems, the COP should be cleared before changing RTI taps. Table 8-1. RTI and COP Rates at 4.096-MHz Oscillator RTI Rate 2.048-MHz Bus RT1 and RT0 Minimum COP Rates 2.048-MHz Bus 2 ms 212 ÷ E00 (215–212)/E 14 ms 4 ms 213 ÷ E01 (216–213)/E 28 ms 8 ms 214 ÷ E10 (217–214)/E 56 ms 16 ms 215 ÷ E11 (218–215)/E 112 ms Freescale Semiconductor, Inc.
