implement 'gettimeofday' and 'time' functions in C library.

continue in deep sleep. Time will be reported at 1 microsecond

resolution. This is the default, and the recommended option.

provide time at microsecond resolution.

resolution. Also the gettimeofday function itself may take

longer to run.

return -1 and set errno to ENOSYS.

When the startup code initializes RTC_SLOW_CLK, it can perform

calibration by comparing the RTC_SLOW_CLK frequency with main XTAL
|

|
|
frequency. This option sets the number of RTC_SLOW_CLK cycles measured
|

|
|
by the calibration routine. Higher numbers increase calibration
|

|
|
precision, which may be important for applications which spend a lot of
|

|
time in deep sleep. Lower numbers reduce startup time.
|

When this option is set to 0, clock calibration will not be performed at

startup, and approximate clock frequencies will be assumed:

- 32768 Hz if the 32k crystal oscillator is used. For this use value 3000 or more.
|

In case more value will help improve the definition of the launch of the crystal.

If the crystal could not start, it will be switched to internal RC.
