Constant embassy_time::TICK_HZ

pub const TICK_HZ: u64 = tick::TICK_HZ; // 1_000_000u64

Ticks per second of the global timebase.

This value is specified by the tick-* Cargo features, which should be set by the time driver. Some drivers support a fixed tick rate, others allow you to choose a tick rate with Cargo features of their own. You should not set the tick-* features for embassy yourself as an end user.
