In the HT49 series how can extended times be internally setup?
Answer The RTC or the Time Base should be considered for use as the timer clock source. In both of these two cases, longer times can be implemented by the timer. As times are longer, corresponding errors may also increase. If the HT49R50A-1/HT49R70A-1 is used, both Timer 0 and Timer 1 can be used together to create a 16-bit timer in the case of the HT49R50A-1 or a 24 bit timer in the case of the HT49R70A-1. The datasheet should be consulted for operational details.
