Reading the CNT register adds two wait states to the register access due to
synchronization delays.

27.3.3 Modulo (TPMx_MOD)
The Modulo register contains the modulo value for the TPM counter. When the TPM
counter reaches the modulo value and increments, the overflow flag (TOF) is set and the
next value of TPM counter depends on the selected counting method (see
).
Writing to the MOD register latches the value into a buffer. The MOD register is updated
with the value of its write buffer according to
to the MOD write buffer are ignored until the register has been updated.
It is recommended to initialize the TPM counter (write to CNT) before writing to the
MOD register to avoid confusion about when the first counter overflow will occur.
