The timer load register K (TLK) is an 8-bit write only register which works to set the reloading
value of the TCK.
When the reloading value is set to the TLK, the value will be simultaneously loaded to the TCK
and the TCK starts counting down from the set value. Also, during an auto reloading operation,
when the TCK underflows, the value of the TLK will be loaded to the TCK. Consequently, the
underflowing cycle can be set within the range of 1 to 256 input clocks. Nonetheless, when the
8-/16-bit of the TMJ is being set to 1 (means when setting is made to 16-bit operation), writing is
possible under the word command only. At this time, the upper 8 bits can be written into the TLK
and the lower 8 bits can be written into the TLJ of the TMJ-1. The TLK and TCK are being
allocated to the same address.
When reset, the TLK is initialized to H'FF.

The MSTPCR are 8-bit read/write twin registers which work to control the module stop mode.
When the MSTP13 bit is set to 1, the Timer J stops its operation at the ending point of the bus
cycle to shift to the module stop mode. For more information, see section 4.5, Module Stop Mode.
When reset, the MSTPCR is initialized to H'FFFF.
Bit 5⎯Module Stop (MSTP13): This bit works to designate the module stop mode for the Timer
J.
