Synopsis
Void RTClk_Init ( void );
Parameters
None.
Return Codes
None.
RTCClk_Control ()
Purpose
Enable or disable the RTC interrupt. If enabled, the interrupt interval must be
specified.
Synopsis
RTCClk_Control ( IN Bbool RTCInt_Enb, IN enum RTC_INTERVAL intv );
Parameters
RTCInt_Enb: Input parameter
Enable (TRUE) or disable (FALSE) the RTC interrupt. If set to Enable when the intv
parameter is set to NO_INT, the RTC interrupt will NOT be enabled.
Intv: Input parameter
The RTC interrupt interval as defined in API_STRUCT_12.h as follows:
HALF_SEC
Interrupt to occur every second.
ONE_SEC
Interrupt to occur every 1 second (default).
TWO_SEC
Interrupt to occur every 2 seconds.
FOUR_SEC
Interrupt to occur every 4 seconds.
EIGHT_SEC
Interrupt to occur every 8 seconds.
NO_INT
No interrupt.
Return Codes
None.
The watchdog timer will give the processor second to respond to an RTC interrupt. If the RTC
interrupt is not serviced within this timeframe, a full reset will be performed.
RTClk_Write ()
Purpose
Initialize the Real Time Clock control, counter, accumulator and trim registers. When
this function is called, the RTC is stopped and restarted.
Synopsis
Void RTClk_Write ( IN struct RTC_t *pRTC );
Where RTC_t is defined as:
struct RTC_t
{
Unsigned char RTCCtl;
Unsigned long RTCCnt;
Unsigned char
RTCAcc[3];
Signed char
RTCTrim[3];
}
Parameters
RTCCtl: Input parameter
BIT[7-6]: not used
BIT[5]: RTCLoad – when set, RTCCnt, RTCAcc and RTCTrim are loaded at the next
32kHz clock positive edge.
BIT[4-3]: Set tic interval as follows:
0x – 1 second
10 – second
11 – 2 seconds
BIT[2-0]: Set interrupt interval as follows:
100 – second
0xx – 1 second
101 – 2 seconds
110 – 4 seconds
111 – 8 seconds
