Trigger Options; Global Timebase; Tpm Interrupts - NXP Semiconductors MKL27Z128VFM4 Reference Manual

29.1.3 Trigger options

Each TPM has a selectable external 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.
TPMx_CONF[TRGSEL]

29.1.4 Global timebase

Each TPM has a global timebase feature controlled by TPMx_CONF[GTBEEN]. TPM1
is configured as the global time when this option is enabled.

29.1.5 TPM interrupts

The TPM has multiple sources of interrupt. However, these sources are OR'd together to
generate a single interrupt request to the interrupt controller. When an TPM interrupt
occurs, read the TPM status registers to determine the exact interrupt source.
