3.8.1.4 Global Timebase
Each TPM has a global timebase feature controlled by the TPMx_CONF[GTBEEN] bit.
TPM1 is configured as the global time when this option is enabled.
3.8.1.5 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.
