HAL timer API

Hardware Abstraction Layer
» List of HAL APIs
» HAL timer API

The HAL must supply at least one timer capable of generating periodic
interrupts. Each timer should generate a separate logical interrupt, and the
interrupt must be latched. The timers must either be variable rate (period is
a multiple of a basic granularity), or be fixed rate (period = 1*granularity).
Optionally, the timer should be capable of reporting the time until the
next interrupt, in units of the granularity.
