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)]

Argument |
Description |
|
I |
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 */ uint16_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.
