    The code supports features to prevent sync loss. There are tuneable parameters that can make the code run well even inthe most demanding situations, although default settings will work excellently in normal operating environments.
    The code supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multshot (5-25us).
    The input signal is automatically detected by the ESC upon power up.
    The code also supports a beacon functionality, where the ESC will start beeping after a given time of zero throttle. This can be very useful for finding lost crafts.

    Stall protection:
    If the motor has attempted to start but not succeeded for a few seconds, it will stop attempting and wait for throttle to be zeroed before attempting again.
    Regenerative braking / active freewheeling:
    Damped light mode is implemented by doing regenerative braking, and inherently active freewheeling is also implemented.Then losses due to braking are counteracted by the reduced losses of active freewheeling.
    Motor PWM:
    The motor PWM frequency is always 24kHz. The resolution is 2048 steps for MCUs running at 48MHz on ESCs that have automatic deadtime control. On ESCs that have fixed deadtime, the PWM resolution is 1024 steps. For MCUs running at 24MHz, the PWM resolutions are half.
    Maximum speeds:
    For ESCs with a 24MHz MCU, maximum speed is limited to 350k eRPM, at which point power to the motor is limited. For ESCs with an MCU running at 48MHz, this number is 500k eRPM.

    SSKaug stated the features of the new BLHeli_S program in the above thread as:

    "BLHeli_S is an improved version of the base BLHeli code.

    BLHeli_S delivers a throttle response that is Smooth as Silk, and the main factor contributing to this, is that it uses hardware to generate motor PWM. Two MCUs support this for BLHeli_S, namely the BusyBee1 at 24MHz (EFM8BB10F8) and the BusyBee2 at 48MHz (EFM8BB21F16).

    BLHeli_S will have the same good Sync holding properties as base BLHeli. Maybe even better.

    BLHeli_S generally does Startup better than base BLHeli.

    BLHeli_S does damped light. Only.

    BLHeli_S has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware. This makes the motor Silent.

    BLHeli_S has very Small throttle Steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.

    BLHeli_S supports very high motor Speeds. A BB1 MCU will support 350k erpm, and the limit of the BB2 is not yet known, so the code is set to limit at 500k erpm.

    BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.
