This part of the MTC contains all the time-related functions. Its architecture is based on an 8-bit shift
left/shift right timer shown in
Figure 92. Overview of MTIM timer in switched and autoswitched mode
1. Register updated on R event.
2. Preload bits, new value taken into account at the next C event (in normal mode) or when a value is written in the MPHST
The MTIM timer includes:
The MTIM timer module can work in two main modes when driving synchronous motors in six-step mode.
