 * Description: description:
    A square wave having a pulse width set in advance by CR010 will generate,
    is output from the TO00 pin as a PPG(Programmable Pulse Generator) signal
    during a cycle set by CR000 when bits 3 and 2 (TMC003 and TMC002)=11 of 16-bit
    timer mode control register 00 (TMC00)(clear & start upon a match between TM00
    and CR000).
    The pulse cycle and duty factor of the pulse generated as the PPG output are as follows.
    . Pulse cycle = (Set value of CR000 + 1) × Count clock cycle
    . Duty = (Set value of CR010 + 1) / (Set value of CR000 + 1)
