• Transfer at valley when valley interrupt is set
Because a new interrupt culling value is transferred when the value of the interrupt culling counter matches
the value of the 16-bit counter, the next interrupt and those that follow occur at the set interval.
For details of rewriting the TABnOPT1 register, see 10.4.3 Interrupt culling function.

Because the register is transferred at the transfer timing of the valley interrupt, a symmetrical triangular
wave is output.
