Description
TIM_ARR is the value to be loaded in the shadow auto-reload register.
The auto-reload register is buffered. Writing or reading the auto-reload register accesses
the buffer register. The content of the buffer register is transfered in the shadow register
permanently or at each UEV, depending on the auto-reload buffer enable bit (TIM_ARBE)
in TMRx_CR1 register. The UEV is sent when the counter reaches the overflow point (or
underflow point when down-counting) and if the TIM_UDIS bit equals 0 in the TMRx_CR1
register. It can also be generated by software. The counter is blocked while the auto-
reload value is 0.
