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

(d) Rewriting TAB1OPT1 register
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 TAB1OPT1 register, see 11.4.3 Interrupt culling function.
