TM00 count value
Disable the timer output inversion operation by match of TM00 and CR010 (TOC004 = 0)
Disable the INTTM010 interrupt (TMMK010 = 1)
Rewrite CR010
Wait for 1 cycle of the TM00 count clock
Enable the timer output inversion operation by match of TM00 and CR010 (TOC004 = 1)
Clear the interrupt request flag of INTTM010 (TMIF010 = 0)
Enable the INTTM010 interrupt (TMMK010 = 0)
