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

|

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.

In modern MCUs, the RTC is usually implement as an internal

peripheral to the MCU. An option is to use an external RTC

connected to the MCU typically via SPI or I2C.

If an external RTC is connect to the MCU through some bus, then the

|
RTC will not be available to the system until after the system

fully boots up and is able to access the bus. In that case, this

setting must be included to suppress attempts to initialize the RTC

early in the boot sequence.
