Ensure ADC conversion is complete before reading ( #11336 )
...
The current Marlin implementation relies on a timer interrupt to start the ADC conversion and read it. However in some circumstances the interrupt can be delayed resulting in insufficient time being available for the ADC conversion. This results in a bad reading and false temperature fluctuations. These changes make sure that the conversion is complete (by checking the ADC hardware via the HAL) before reading a value.

[2.0.x] Small assorted collection of fixes and improvements ( #10911 )
...
* Misc fixes and improvements
- Get rid of most critical sections on the Serial port drivers for AVR and DUE. Proper usage of FIFOs should allow interrupts to stay enabled without harm to queuing and dequeuing.
Also, with 8-bit indices (for AVR) and up to 32-bit indices (for ARM), there is no need to protect reads and writes to those indices.
- Simplify the XON/XOFF logic quite a bit. Much cleaner now (both for AVR and ARM)
- Prevent a race condition (edge case) that could happen when estimating the proper value for the stepper timer (by reading it) and writing the calculated value for the time to the next ISR by disabling interrupts in those critical and small sections of the code - The problem could lead to lost steps.
- Fix dual endstops not properly homing bug (maybe).
* Set position immediately when possible

Add memory barrier, optimal interrupt on-off
...
Disabling an ISR on ARM has 3 instructions of latency. A Memory barrier is REQUIRED to ensure proper and predictable disabling. Memory barriers are expensive, so avoid disabling if already disabled (See https://mcuoneclipse.com/2015/10/16/nvic-disabling-interrupts-on-arm-cortex-m-and-the-need-for-a-memory-barrier-instruction/ )

Various fixes for DUE... ( #10152 )

- Watchdog reset during SD Card initialization.
- Move `DebugMonitor` to `DebugMonitor_Due.cpp`.
- Since the watchdog is enabled on boot do extra resets during init.
- Have `thermalManager` do watchdog reset before its ISR starts to prevent reset.
- Ensure that timers are stopped before reprogramming them to address tone issues.
- Improve SAM3XE reset when reflashed through the native port.
