1.8.1.2 Clock options
The TPM blocks are clocked from a single TPM clock that can be selected from
OSCERCLK, MCGIRCLK, MCGPLLCLK/2, or MCGFLLCLK . The selected source is
controlled by SIM_SOPT2[TPMSRC] and SIM_SOPT2[PLLFLLSEL].
Each TPM also supports an external clock mode (TPM_SC[CMOD]=1x) in which the
counter increments after a synchronized (to the selected TPM clock source) rising edge
detect of an external clock input. The available external clock (either TPM_CLKIN0 or
TPM_CLKIN1) is selected by SIM_SOPT4[TPMxCLKSEL] control register. To
guarantee valid operation the selected external clock must be less than half the frequency
of the selected TPM clock source.
1.8.1.3 Trigger options
Each TPM has a selectable trigger input source controlled by TPMx_CONF[TRGSEL] to
use for starting the counter and/or reloading the counter. The options available are shown
in the following table.
