Functional description
43.5.1 PWT counter and PWT clock pre-scaler
The pulse width timer (PWT) measures duration of a pulse or the period of a signal input
to the PWTIN by a 16-bit free running counter (PWT_CNTH:L). There is a clock pre-
scaler (CLKPRE) in PWT module that provides the frequency divided clock to the
PWT_CNTH:L.. The clock pre-scaler can select clock input from bus clock and
alternative clock by PWT_CR[PCLKS].
