Cycle
Bit 2 ~ Bit 7 (undefined): These bits are not used. However, these bits must be
cleared to “0” to avoid possible error.

The contents of this register is PWM1 time base period. The PWM1 frequency is the
inverse of the time base period.

A specified value keeps the PWM2 output to remain high until the it matches with the
value of TMR2.
