Functional Description and Application Information
4.18.4
4.18.4.1
This section provides a complete functional description of the timer TIM16B4C block. Refer to the detailed timer block diagram
in
4.18.4.2
The prescaler divides the bus clock by 1, 2, 4, 8, 16, 32, 64, or 128. The prescaler select bits, PR[2:0], select the prescaler divisor.
PR[2:0] are in the timer system control register 2 (TSCR2).
