Hi to all. I am trying to view through ASC0 the actual time of the RTC on my XC16x board (XC164CS microcontroller). I need a procedure to capture all values of both timer registers. (RTC_RTCH and RTC_RTCL) The RTC initialization is as follows:
SYSCON0_RTCCM = 0; // enable access to control bits /// ----------------------------------------------------------------------- /// Configuration of the RTC Counter: /// ----------------------------------------------------------------------- /// - RTC input frequency is 345,600 kHz /// - the input clock is divided by factor 8 /// - counter is started after initialization while((RTC_CON & 0x8000) == 0x0000); // wait until access is possible RTC_CON = 0x0002; // load RTC control register /// - overflow period on T14: 1,0000 [s] /// - overflow period on CNT0: 1,0000 [s] /// - overflow period on CNT1: 1,0000 [min] /// - overflow period on CNT2: 1,0000 [h] /// - overflow period on CNT3: 1,0000 [days] RTC_T14REL = 0x5740; // load T14 count/reload register RTC_RTCL = 0x13FF; // load RTC low register RTC_RELL = 0x13FF; // load RTC reload low register RTC_RTCH = 0xFA04; // load RTC high register RTC_RELH = 0xFA04; // load RTC reload high register /// ----------------------------------------------------------------------- /// Configuration of the used RTC Interrupts: /// ----------------------------------------------------------------------- /// RTC service request node configuration: /// - RTC interrupt priority level (ILVL) = 15 /// - RTC interrupt group level (GLVL) = 1 /// - RTC group priority extension (GPX) = 0 RTC_IC = 0x007D; /// Use PEC channel 5 for RTC INT: /// - normal interrupt /// - pointers are not modified /// - transfer a word /// - service End of PEC interrrupt by a EOP interrupt node is disabled PECC5 = 0x0000; // load PECC5 control register RTC_ISNC = 0x0155; // load RTC interrupt sub node register RTC_CON_RUN = 1; // starts the counter } // End of function RTC_vInit
Thanks :)
