The timer R control/status register (TMRCS) works to control the interrupts of timer R.
The TMRCS is an 8-bit read/write register. When reset, the TMRCS is initialized to H'03.
Bit 7    Enabling the TMRI3 Interrupt (TMRI3E): This bit works to permit/prohibit occurrence
of the TMRI3 interrupt when an interrupt cause being selected by the CP/SLM bit of the TMRM2
has occurred, such as occurrences of the TMRU-2 capture signals or when the slow tracking
mono-multi processing ends, and the TMRI3 has been set to 1.
