MTIM Count — These eight read-only bits contain the current value of the 8-bit counter. Writes have no effect to
this register. Reset clears the count to $00.
MTIM Modulo — These eight read/write bits contain the modulo value used to reset the count and set TOF. A value
of $00 puts the MTIM in free-running mode. Writing to MTIMxMOD resets the COUNT to $00 and clears TOF. Reset
sets the modulo to $00.
