TIM1 main features

TIM1 timer features include:
•
16-bit up, down, up/down auto-reload counter.
• 16-bit programmable prescaler allowing dividing (also "on the fly") the counter clock
frequency either by any factor between 1 and 65536.
•
Up to 4 independent channels for:
–
–
–
–
•
Complementary outputs with programmable dead-time
•
Synchronization circuit to control the timer with external signals and to interconnect
several timers together.
•
Repetition counter to update the timer registers only after a given number of cycles of
the counter.
• Break input to put the timer's output signals in reset state or in a known state.
•
Interrupt/DMA generation on the following events:
–
–
–
–
–
•
Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
purposes
•
Trigger input for external clock or cycle-by-cycle current management
