Assuming that the set value = n, the “H” level width of the one-shot pulse is expressed
n

as follows :
fi: Frequency of count source
Note: Use the MOVM or STA(STAD) instruction for writing to this register.
Writing to this register must be performed in a unit of 16 bits.

Notes 1: Use the MOVM or STA (STAD) instruction for writing to this register. Additionally, make sure writing to this register
must be performed in a unit of 16 bits.
2: This register is valid only in three-phase mode 1 of the three-phase waveform mode.
