R_RTC_Set_CounterValue

Sets the counter value (year, month, weekday, day, hour, minute, second) of the real-time clock.

[Syntax]

#include    "r_cg_macrodriver.h"

#include    "r_cg_rtc.h"

MD_STATUS   R_RTC_Set_CounterValue ( rtc_counter_value_t counter_write_val );

[Argument(s)]

I/O

Argument

Description

rtc_counter_value_t

  counter_write_val;

Counter value

Remark

Below is an example of the structure rtc_counter_value_t (counter value) for the real-time clock.

typedef struct {

    uint8_t sec;    /* second */

    uint8_t min;    /* Minute */

    uint8_t hour;   /* Hour */

    uint8_t day;    /* Day */

    uint8_t week;   /* Weekday (0: Sunday, 6: Saturday) */

    uint8_t month;  /* Month */

    uint8_t year;   /* Year */

} rtc_counter_value_t;

[Return value]

Macro	Description
MD_OK	Normal completion
MD_BUSY1	Executing count process (before change to setting)
MD_BUSY2	Stopping count process (after change to setting)

Remark

If MD_BUSY1 or MD_BUSY2 is returned, it may be because the counter-operation is stopped, or the counter operation start wait time is too short, so make the value of the RTC_WAITTIME macro defined in the header file "r_cg_rtc.h" larger.
