TM00 count value
using the following procedure.
<1> Disable the timer output inversion operation by match of TM00 and CR01 (TOC004 = 0)
<2> Disable the INTTM01 interrupt (TMMK01 = 1)
<3> Rewrite CR01
<4> Wait for 1 cycle of the TM00 count clock
<5> Enable the timer output inversion operation by match of TM00 and CR01 (TOC004 = 1)
<6> Clear the interrupt request flag of INTTM01 (TMIF01 = 0)
<7> Enable the INTTM01 interrupt (TMMK01 = 0)
