NXP Semiconductors KL25 Series - Modulo (Tpmx_Mod)

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

31.3.3 Modulo (TPMx_MOD)
The Modulo register contains the modulo value for the LPTPM counter. When the
LPTPM counter reaches the modulo value and increments, the overflow flag (TOF) is set
and the next value of LPTPM counter depends on the selected counting method (see
Counter ).
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 MOD Register Update .
It is recommended to initialize the LPTPM counter (write to CNT) before writing to the
MOD register to avoid confusion about when the first counter overflow will occur.
