16.3.2
The two read-only TPM counter registers contain the high and low bytes of the value in the TPM counter.
Reading either byte (TPMCNTH or TPMCNTL) latches the contents of both bytes into a buffer where they
remain latched until the other byte is read. This allows coherent 16-bit reads in either order. The coherency
mechanism is automatically restarted by an MCU reset, a write of any value to TPMCNTH or TPMCNTL,
or any write to the timer status/control register (TPMSC).
Reset clears the TPM counter registers.

The maximum frequency that is allowed as an external clock is one-fourth of the bus
frequency.
If the external clock input is shared with channel n and is selected as the TPM clock source,
the corresponding ELSnB:ELSnA control bits should be set to 0:0 so channel n does not try
to use the same pin for a conflicting function.
