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

timer provides for higher resolution time.

|

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.
