29.1.1 TPM instantiation information
This device contains three low power TPM modules (TPM). All TPM modules in the
device are configured only as basic TPM function, do not support quadrature decoder
function, and all can be functional in Stop/VLPS mode. The clock source is either
external or internal in Stop/VLPS mode.
The following table shows how these modules are configured.

There are several connections to and from the TPMs in order to facilitate customer use
cases. For complete details on the TPM module interconnects please refer to the
29.1.2 Clock options
The TPM blocks are clocked from a single TPM clock that can be selected from
OSCERCLK, MCGIRCLK, or MCGPCLK. The selected source is controlled by
SIM_SOPT2[TPMSRC] .
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.
