Notes 1: Valid when the W-phase output fix bit (bit 0 at address A816) = “1.” Be sure not to change the value during output of a

fixed value.

2: Valid when the V-phase output fix bit (bit 1 at address A816) = “1.” Be sure not to change the value during output of a

fixed value.

3: Valid when the U-phase output fix bit (bit 2 at address A816) = “1.” Be sure not to change the value during output of a

fixed value.

Invalid in the three-phase waveform mode.

Invalid in pulse output port mode.
