Implementations
Bit 0 - Counter enable Note: External clock, gated mode and encoder mode can work only if the CEN bit has been previously set by software. However trigger mode can set the CEN bit automatically by hardware. CEN is cleared automatically in one-pulse mode, when an update event occurs.
Bit 1 - Update disable This bit is set and cleared by software to enable/disable UEV event generation. Counter overflow/underflow Setting the UG bit Update generation through the slave mode controller Buffered registers are then loaded with their preload values.
Bit 2 - Update request source This bit is set and cleared by software to select the UEV event sources. Counter overflow/underflow Setting the UG bit Update generation through the slave mode controller
Bit 4 - Direction Note: This bit is read only when the timer is configured in Center-aligned mode or Encoder mode.
Bits 5:6 - Center-aligned mode selection Note: It is not allowed to switch from edge-aligned mode to center-aligned mode as long as the counter is enabled (CEN=1)
Bits 8:9 - Clock division This bit-field indicates the division ratio between the timer clock (CK_INT) frequency and sampling clock used by the digital filters (ETR, TIx),
Bit 11 - UIF status bit remapping
