config RTC_DATETIME |

bool "Date/Time RTC Support" |

default n |

depends on RTC |

---help--- |
|
There are two general types of RTC: (1) A simple battery backed counter |
|
that keeps the time when power is down, and (2) a full date / time RTC the |
|
provides the date and time information, often in BCD format. If |
|
RTC_DATETIME is selected, it specifies this second kind of RTC. In this |
|
case, the RTC is used to "seed" the normal NuttX timer and the NuttX system |
|
timer provides for higher resolution time. |

|
|
config RTC_HIRES |
|
bool "Hi-Res RTC Support" |
|
default n |
|
depends on RTC && !RTC_DATETIME |
|
---help--- |
|
If RTC_DATETIME not selected, then the simple, battery backed counter is |
|
used. There are two different implementations of such simple counters |
|
based on the time resolution of the counter: The typical RTC keeps time |
|
to resolution of 1 second, usually supporting a 32-bit time_t value. In |
|
this case, the RTC is used to "seed" the normal NuttX timer and the NuttX |
|
timer provides for higherresoution time. |
|
|
|
If RTC_HIRES is enabled in the NuttX configuration, then the RTC provides |
|
higher resolution time and completely replaces the system timer for purpose |
|
of date and time. |

config RTC_FREQUENCY |

int "Hi-Res RTC frequency" |

default 1 |

depends on RTC && !RTC_DATETIME && RTC_HIRES |

to be one Hz. |
