Basic Function Timer (BFTM)

Introduction

The Basic Function Timer Module, BFTM, is a 32-bit up-counting counter designed to measure
time intervals, generate one shot pulses or generate repetitive interrupts. The BFTM can operate
in two modes which are repetitive and one shot modes. The repetitive mode restarts the counter at
each compare match event which is generated by the internal comparator. The BFTM also supports
a one shot mode which will force the counter to stop counting when a compare match event occurs.
