The tick count corresponds to the tick count used by the RTOS for timing
|

purposes. It increments monotonically from 0 at boot, hence effectively
|
|
never wraps. If the underlying RTOS only provides a 32-bit tick count,

this method expands it to 64 bits.

@note mbed OS always uses millisecond RTOS ticks, and this could only wrap
|

after half a billion years
|

@note You cannot call this function from ISR context.
