• Select clock source (same as RTC) in the configuration options • Select Time Base frequency from the formula: For HTG2150, HTG2160, HTG2190 and HTG21A0, fTIME BASE=32768Hz/(2×2(TMR3C)), where TMR3C=0~7; For HTG2130, fTIME BASE=512Hz/(2×2(RTCC)), where RTCC=0~7; • Enable the corresponding interrupt by setting the ETBI bit to 1. If the Time Base overflows, an internal interrupt request will be issued.
