This setting defines which hardware timers are used to
|
|
implement 'gettimeofday' and 'time' functions in C library.
|
|
|
|
- If both high-resolution (systimer) and RTC timers are used, timekeeping will
|
|
continue in deep sleep. Time will be reported at 1 microsecond
|
|
resolution. This is the default, and the recommended option.
|
|
- If only high-resolution timer (systimer) is used, gettimeofday will
|
|
provide time at microsecond resolution.
|
|
Time will not be preserved when going into deep sleep mode.
|
|
- If only RTC timer is used, timekeeping will continue in
|
|
deep sleep, but time will be measured at 6.(6) microsecond
|
|
resolution. Also the gettimeofday function itself may take
|
|
longer to run.
|
|
- If no timers are used, gettimeofday and time functions
|
|
return -1 and set errno to ENOSYS.
|
|
- When RTC is used for timekeeping, two RTC_STORE registers are
|
|
used to keep time in deep sleep mode.

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:
|
|
|
|
- 150000 Hz if internal RC oscillator is used as clock source. For this use value 1024.
|
|
- 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.

light sleep, with specific condition

- GPIO needs to be configured as input-mode only
|

- The pin receives a small electrostatic pulse, and reset occurs when the pulse
|
|
voltage is higher than 6 V
|
|
|
|
For GPIO set to input mode only, it is not a good practice to leave it open/floating,
|
|
The hardware design needs to controlled it with determined supply or ground voltage
|

is necessary.
|
|

This option provides a software workaround for this issue. Configure to isolate all

|
GPIO pins in sleep state.
