— If the enhanced prescaler is selected (EPSCKE = 1), the EPSCK bits select a value by which
— The output of either the standard prescaler or the enhanced prescaler is then divided by 1, 2, 4,
— If the TPUMCR2[DIV2] bit is one, the TCR1 counter increments at a rate of the internal clock
the system clock is divided. The lowest frequency for TCR1 clock is system clock divided by
64x8. The highest frequency for TCR1 clock is system clock divided by two (2x1). See
Table 19-2

divided by two. If DIV2 is zero, the TCR1 increment rate is defined by the output of the TCR1
prescaler (which, in turn, takes as input the output of either the standard or enhanced prescaler).
