27 High-resolution timer (HRTIM)
27.1 Introduction
The high-resolution timer can generate up to 12 digital signals with highly accurate timings.
It is primarily intended to drive power conversion systems such as switch mode power
supplies or lighting systems, but can be of general purpose usage, whenever a very fine
timing resolution is expected.
Its modular architecture allows to generate either independent or coupled waveforms. The
wave-shape is defined by self-contained timings (using counters and compare units) and a
broad range of external events, such as analog or digital feedbacks and synchronization
signals. This allows to produce a large variety of control signal (PWM, phase-shifted,
constant Ton,...) and address most of conversion topologies.
For control and monitoring purposes, the timer has also timing measure capabilities and
links to built-in ADC and DAC converters. Last, it features light-load management mode and
is able to handle various fault schemes for safe shut-down purposes.
