+//! Time driver using Periodic Interrupt Timer (PIT)
+//!
+//! This driver is used with the iMXRT1xxx parts.
+//!
+//! The PIT is run in lifetime mode. Timer 1 is chained to timer 0 to provide a free-running 64-bit timer.
+//! The 64-bit timer is used to track how many ticks since boot.
+//!
+//! Timer 2 counts how many ticks there are within the current u32::MAX tick period. Timer 2 is restarted when
+//! a new alarm is set (or every u32::MAX ticks). One caveat is that an alarm could be a few ticks late due to
+//! restart. However the Cortex-M7 cores run at 500 MHz easily and the PIT will generally run at 1 MHz or lower.
+//! Along with the fact that scheduling an alarm takes a critical section worst case an alarm may be a few
+//! microseconds late.
+//!
+//! All PIT timers are clocked in lockstep, so the late start will not cause the now() count to drift.
