Correct the period by adding 1 to electrical angle counts 16 for “n” times. The timer counts
the electrical angle period set value “m”’for (16 − n) times and counts (m + 1) for “n” times
Set the electrical angle period.
Read the electrical angle. This register can also be set to initialize or correct the angle while
counting. Any value greater than 0x17F cannot be set.
Set the voltage amplitude. The waveform arithmetic circuit multiplies the data set here by
the sine wave data read out from the sine wave RAM. The amplitude has its upper limit
determined by the set value of the MDPRD register when performing this multiplication.
Capture the value from the electrical angle timer when the position is detected.
To initialize the entire RAM data of the sine wave table, set the addresses at which to set,
sequentially from 0x000 to 0x17F, in the ELDEG register, and write waveform data to the
WVFMDR register each time. Make sure the waveform arithmetic circuit is disabled when
writing this data.
To read data in the sine waveform table (data RAM), write WVFMAD register to address
value, and read WVFMDR register.
Write data to sine waveform table, or read data in sine waveform table.
Write: Set the addresses at which to set, sequentially from 0x000 to 0x17F, in the ELDEG
register, and write waveform data to the WFMDR register each time. Make sure the wave-
form arithmetric circuit is disabled when writing this data.
Read: Set the address value (0x000 to 0x17F) in the WVFMAD, and read WVFMDA reg-
ister.
Set 3-phase waveform data, send it to the waveform arithmetic circuit. Continuously write
U,V,W 3-phase waveform data in TRPWVDR register order.
